    Apr 6, 2020
    Switching regulator circuits have been around for many years and users have always had a choice between designing their own using discrete components or buying a finished...

    All AC/DC converters contain a built-in fusible device (either one or more fuses or a fusible resistor), so no external protection is normally necessary. However, some regulations require an external input fuse to protect against short circuits in the AC cabling or PCB tracks leading to the converter. The –ST or RAC-ADAPT options (PCB with screw terminal input and output connections) also contain an external input fuse as standard.
    AC/DC converters can tolerate a DC voltage on their outputs when they are not powered up as long as the external DC voltage is lower than their nominal DC output. Therefore the output from the AC/DC adaptor should be connected to an alternate DC supply via OR-ing diodes. This is a useful feature that enables, for example, a board to be powered up and calibrated or tested using a safe low voltage DC bench supply and then only plugged into the mains for a final check after the unit has been reassembled into its case.
    All of our AC/DC converters contain a built-in Under Voltage Lock-Out (UVLO) function that will disable the converter if the input voltage is too low to stop the input current getting too high. The UVLO is typically set to around 80V AC.
    The main output options are:

    Single output, with Vout+ and Vout- pins. This is the most commonly used option.
    Dual (bipolar) output, with Vout+, Com and Vout- pins, e.g. +/-15V. Useful for generating bipolar supply rails from a single input voltage rail, e.g, to supply an op-amp.
    Dual (asymmetric) output , with Vout+, Com and Vout- pins, e.g. +18/-9V. Useful for IGBT gate driver applications which uses asymmetric supply voltages.
    Dual (independent) output, with Vout1+, Vout1- and Vout2+, Vout2-, where the outputs are isolated both from the input and from each other. Useful for supplying a two-channel application using only one converter.
    Triple output, with a main Vout+ and Aux+, Com and Aux- pins, e.g. +5V and +/-12V. Useful for applications requiring a single high current supply and an auxiliary supply to power peripherals.
    DC/DC converters are not reverse polarity protected. They will be irreparably damaged if connected the wrong way around. If it is possible or likely that the converter could be reverse polarity connected, then a diode must be used to protect the converter (refer to the Application Notes).
    All DC/DC converters can withstand occasional short-duration over-voltage transients (<100ms), but repeated over-voltage conditions can lead to failure. Unregulated DC/DC converters can cope with longer input over-voltage conditions as long as the supply voltage does not exceed the component ratings. The output voltage will also be too high. Regulated DC/DC converters will attempt to regulate an input over-voltage condition so will be more stressed, nevertherless some converters like the REC3.5 and REC6 can withstand 60s input over-voltage conditions (refer to datasheet for limits)
    All DC/DC converters can withstand occasional short-duration brown-outs, but repeated under-voltage conditions can lead to failure. For a constant power load, the input current rises exponentially as the input voltage decreases. Unregulated DC/DC converters can cope with longer input under-voltage conditions as long as the increased input current does not exceed the component ratings. The output voltage will also be too low. Unregulated converters do not have an Under-Voltage Lock-Out (UVLO) function. Regulated DC/DC converters will attempt to regulate an input under-voltage condition so will be more stressed, some series are available with an Under-Voltage Lock-Out (UVLO) function, either as standard or as an /X1 option, which disables the converter if the input current is too high. This also stops the converter from attempting to start up too early before the supply voltage has stabilized.
    The ratio refers to the input voltage range. For example, a 24V input DC/DC converter with 1:1 input range is specified with 24Vinput +/-10% (21.6V to 26.4V). A 24V input DC/DC converter with 2:1 input range is specified over a two-to-one input voltage range of 18V-36V and a 24V input DC/DC converter with 4:1 input range is specified over a four-to-one input voltage range of 9V-36V.
    A non-isolated or switching regulator converter can efficiently reduce or boost a DC input voltage to a lower or higher output voltage.

    A switching regulator has the following advantages over an isolated DC/DC converter:

    1. As a transformer is not used and the input and output share a common ground, the efficiencies can be very high (>97%). These low losses allow a wider operating temperature and a higher power density compared with isolated converters.
    2. A switching regulator can vary the internal on/off duty cycle over a wider range to compensate for changes in load and/or input voltage, thus the converter can work efficiently over an extended input voltage range (7:1 or more) and load range (100:1).
    3: Switching regulators often uses a cycle-by-cycle controller IC, so the reaction time to dynamic load changes or short circuit conditions is very fast.
    An isolated DC/DC converter will translate a DC input voltage to the same or a different DC output voltage which is electrically isolated from the input via an internal transformer. It is commonly used for the following reasons:

    1: To break ground loops. Electrical interference on the power rails is blocked from affecting other parts of the circuit, for example, a DC/DC used in a motor controller circuit can provide a low-noise, stable output from a noisy DC supply.
    2: To change the reference point of a supply. For example to generate a +5V rail from a -48V telecoms power supply.
    3. For safety. For example in medical applications to protect the patient from power supply faults
    4: For supply security. For applications with multiple channels, isolating each channel power supply with a separate DC/DC converter means that if any channel is faulty or short-circuited, the remaining channels are unaffected.
    A DC/DC converter can have the following connections:

    The supply pins, Vin+ and Vin –
    The output pins, Vout + and Vout- (plus a common pin for +/- outputs)
    A remote control on/off, enable or control pin (usually labelled "CTRL")
    A trim pin (to adjust the output voltage up or down)
    Sense pins (to compensate for any cable or track resistance losses)
    Power OK pin (an output signal to indicate that the output voltage is stable)
    There are many reasons why you should use a DC/DC converter, but the most common applications are:

    • To match the loads to the power supply (e.g. to generate higher, lower or dual outputs from a single source, or to invert a supply rail.)
    • To isolate primary and secondary circuits (e.g. for safety reasons or to protect a sensitive circuit from interference)
    • To simplify power supplies (e.g. multiple output converters or one converter per rail (point-of-load) can reduce power supply complexity, overall cost and board space requirements while at the same time increasing flexibility, reliability and system efficiency.)
    All RECOM products are RoHS2+ compliant. You can find certificates and Declarations of Conformity on our home page.
    Although some of our DC/DC converters contain Class A or Class B EMC filters built in, many of our low cost DC/DC converters contain only simple input filters. The customer can then decide to add an EMC filter individually or for all of the converters together to save costs. External EMI filter suggestions are given in our Application Notes for both Class A and Class B levels. All of our AC/DC converters contain a built-in Class B EMC filter as standard.
    RECOM prides itself on having a comprehensive certification portfolio, with full third party UL/IEC/EN certifications (not just 'designed to meet'). Certifications cover Industrial, Medical, LED lighting, Household, Railway and Automotive standards, depending on the application area of the converter.
    We provide many medical grade converters with UL/IEC/ EN-60601-1 certifications (3rd Ed.), including risk assessment documentation.
    The UKCA (UK Conformity Assessed) marking is a new UK product marking that is used for products being placed on the market in Great Britain (England, Wales and Scotland). It applies to the same products that are currently CE marked. The circumstances in which self-declaration of conformity for UKCA marking can be used are the same as for CE marking. Based on current UK rules, RECOM is eligible to self-declare for the UKCA Declaration of Conformity (DoC) as long as the EU and UK regulations remain aligned.
    RECOM will make available a separate UKCA Declaration of Conformity (DoC) based on the existing CE Declaration of Conformity (DoC) and test reports (self-declaration). CE marking remains valid for goods placed on the market in Great Britain until 1 January 2023. The UKCA marking must be used for placing goods on the market in Great Britain after this date. RECOM will continue to actively monitor any changes to the UKCA rules based on UK government guidance and react accordingly.
    We will also instigate a program to successively add the UKCA mark to our CE marked products to fulfil our obligations as manufacturer. For further information or enquiries regarding our UKCA policy, contact TechSupport
    Ultrasonically cleaning can cause damage to sensitive electronic components, so it is not recommended. Nevertheless, some RECOM parts can be cleaned without harm, so if ultrasonic cleaning is necessary, please contact Recom Technical Support for advice.
    As with all electronic devices, strongly reactive or abrasive cleaners can attack the encapsulating material and the pins, hence cleaning is recommended with inert solutions (e.g. alcohol or water based solvents) suitable for electronic components and at the temperatures recommended by the cleanser manufacturer. Jet washing or ultrasonic cleaning is not recommended.
    Refer to the instructions given by the conformal coating supplier regarding the recommended process for washing and drying the boards before applying the conformal coating. We have never received any complaints of chemical incompatibility or any other problems with conformal coating our products.
    In addition to the standard ranges shown in the data sheet, RECOM has the capability to produce custom AC/DC and DC/DC converters designed to your specific requirements.
    In general, there are two customizations available: modification of an existing product or a full custom.
    Modified parts can be quickly designed to ""tweak"" the specifications to better fit the application, for example, a non-standard output voltage or extra long pins. Prototype samples can also be produced in short timescales, often with a minimal increase in cost.
    Full custom is a new design with a different shape, specification or additional outputs, for example. An NRE (Non-Returnable Engineering) charge will usually be required and a Minimum Order Quantity (MOQ). Contact Recom Technical Support for more information.
    For normal function, no external capacitors are required for normal operation, unless specified in the datasheets. For EMI filtering, consult our recommendations in our Application Notes.
    All RECOM production batches are burn-in tested in our factory before being shipped to the customer.
    The inrush current is dependent on the converter, the load (especially the capacitive load) and the impedance of the primary power supply. Therefore, there is no recommended value for the inrush limiting inductor as this need to be individually worked out for each application. Having said that, usually 22µH~100µH is a good starting point.
    A CMC is a good inrush current limiter because the core does not go into saturation with high currents (the +ve inrush current is balanced out by the -ve inrush current), so it has a dual purpose: EMC filter and inrush limiting. However, for high power converters it is sometimes better to use a low inductance, high current, choke that is selected to reduce inrush rather than a high inductance choke selected for the best EMC filtering because otherwise too much power could be lost through the choke's resistance during normal operation.
    Recom does not offer this feature in any of its DC/DC converters. Synchronizing the oscillators in several converters is a useful technique where beat frequencies must be avoided at the cost of an increased amount of interference at the main frequency. Usually effective results can be achieved by individually filtering each converter without creating a strongly interfering main frequency.
    In theory, yes, but in practice it is very non-linear. Adjusting the output voltage using an external voltage or current can also affect the regulation and short circuit behaviour, so it is not recommended.
    Our AC/DC converters usually incorporate input surge protection, although some series require an external suppression MOV to meet all operating conditions. Our DC/DC converters do not usually incorporate surge protection, although an electrolytic capacitor placed close to the input pins is usually sufficient to meet the requirements of 61000-4-5.
    Reverse polarity protection is not built inside any of the converters. It needs to be added externally. We recommend adding an external MOSFET for higher power converters or a simple blocking diode for lower power, non-critical applications.
    RECOM has one of the largest selection of non-isolated DC/DC products on the market. Our search engine allows searches for non-isolated converters only.
    An isolated DC/DC converter has no electrical connection between the input and output. So it does not matter if Vin+ is connected to a positive supply and Vin- is connected to ground or if Vin+ was connected to ground and Vin- was connected to a negative supply. This is useful in the telecommunications industry, for example, where a standard -48V supply can be used to generate a +5V output (Vin+ = ground, Vin- = -48V, Vout + = 5V, Vout- = ground).
    This does not apply to non-isolated switching regulators, but the R-78 series can be configured to generate a negative output voltage from a positive input voltage (refer to the Application Notes).
    The main problem with a 12 battery as a power source is that it can deliver very high inrush currents. Normally with lower power converters (under 20W), this is not a problem, but for the higher power converters the inrush current can damage the converters or extzernal components. The other issue with batteries is if the end-user connects the battery the wrong way around, this will instantly destroy any converter. To avoid these problems, an external blocking diode or FET can be fitted and either a soft-start circuit or an inrush current filter can be added. Please contact Recom Technical Support for suggested circuits and component values.
    The unregulated converters have a deviation curve depending on the load. The lower the load is, the higher the output voltage. Please check the graphs included in our Datasheets about Deviation/Load. Usually, these converters need at least 20% load.
    RECOM prides itself on having comprehensive datasheets, but there may be a parameter or operating characteristic that it not listed.

    We offer local Technical Support through our offices in Austria, Germany, USA, Singapore, Japan and China, or you can contact your local RECOM contact or distributor to ask us for more information.
    The converters have a derating curve that starts usually between 70°C and 85°C. From that temperature point onwards the load must be reduced to limit the internal heat dissipation. You can use a heat sink to move this temperature point up a few degrees, but if your application doesn’t have an adequate cooling system, even a large heat sink may not be effective. Plastic cased converters cannot be effectively heatsinked. Use a higher power converter instead to increase the derating.
    You can use a dual 15V output converter (+/-15V), omitting the common pin and using only the +Vout pin and –Vout pins. Dual output converters regulate between the +ve and –ve output rails only, so connection to the common pin is unnecessary for the converter to work normally. This is true of any dual output converter, so +/-5V = 10V, +/-9V = 18V, +/-12V = 24V and +/-15V = 30V.

    If isolation is not required, the –ve output pin can be connected back to the +ve input pin to boost a supply voltage. For example, a 24V supply feeding an isolated 24Vin, 24V out DC/DC converter wired up this way will generate a 48V output voltage with double the power: 24V@1A (24W) from the supply + 24V@1A (24W) from the converter = 48V@1A (48W)
    The Remote On/Off or Control pin is commonly used for the following reasons:
    To control a high-power converter using a low-power signal. The input power of a control pin is typically only a few milliwatts, but it can enable or disable a converter of as much as a hundred watts. This means that the low power output of a microcontroller or logic IC can be used to control a system without the need of extra amplifiers or bulky relays.
    To power-up or power-down a system of several converters in the right sequence. Many complex power supplies need to start up or shut down in a certain order to be safe. An example could be a computer-based controller where the microprocessor should be up and running before the peripherals are powered up. Another example is where one power supply feeds another. The primary power supply often should have reached a stable output voltage before the secondary power supplies are turned on.
    To save energy. A control pin can be used to turn off the power completely to parts of a circuit during standby mode, while leaving a central watchdog circuit still active. This is especially important for battery powered circuits because all DC/DC converters draw some power even when they are not loaded.
    To reduce the inrush current. In a system of several parallel sub-systems, it is often useful to stagger the start-up of each sub-system so as not to overload the primary power supply or cause the main fuse to trip or blow on switch-on.
    The trim pin (if fitted) can be used to increase or decrease the regulated output voltage over a limited range (typically +/-10% or -20%, +10%). Some switching regulators offer a Vadj. pin which can adjust the output voltage over a wider range (up to +/-50%).
    Connecting a resistor between trim (or Vadj,) and the Vout+ pin will reduce the output voltage. Connecting a resistor between trim (or Vadj,) and the Vout- or Gnd pin will increase the output voltage.
    Trimming is typically used to help compensate for the voltage drop along a long cable or PCB track by increasing the output voltage, or to reduce the output voltage to avoid over-voltage stress on the load under worst-case conditions.
    Voltage trim is also useful to match different battery chemistries. A 12V lead acid battery can be trickle charged using a 12V converter trimmed up to 13.2V (+10%) or a LiPo Battery safely charged from a 5V converter trimmed down to 4.6V (-8%).
    The sense pins (Sense + and Sense-) are used by the DC/DC converter to regulate the output voltage as delivered to the load, not as measuresd directly across the output pins. The converter uses four connections, Vout+ and Vout- delivering a high current and two low current connections, Sense+ and Sense- for feedback. The advantage of using the sense pins compared with simply trimming up the output voltage to compensate for the volt-drop along the connection is that sense pins regulate the load voltage at both low and high load currents, thus avoiding too high a load voltage when lightly loaded. Sense pins can also be used by some load sharing controllers to allow two or more DC/DC converters to be connected in parallel to increase the power.
    Some unregulated bipolar converters feature power sharing, where all or some of the load can be taken from just one output pin.
    Regulated dual output converters regulate the difference between Vout+ and Vout- and allow the common pin to float. So if a +/-15V is asymmetrically loaded with, say +80%, -20%, then the output voltage difference will stay 30V, but the common pin will drift so that the output voltage will measure +13, -17V. If a balanced output is required with unbalanced load, then use post-regulation to stabilize the outputs.
    When a control pin voltage is rising, the switching point (threshold) is higher than when the voltage is falling. The difference between the rising voltage trigger point and the falling voltage trigger point is the hysteresis. For example, a converter with negative control logic could switch on as soon as the control pin voltage exceeds 3V but once started, only switches off again when the voltage drops below 1V. The 2V difference is the hysteresis and stops the converter from switching on-and-off erratically with a slowly rising or falling control voltage.
    Some RECOM converters, like the R-78AA series, have a two level control pin function. If the control pin voltage drops below 2.6V, the main power stage is switched off, but the internal oscillator and voltage regulator is kept running. This allows a very rapid restart from standby to full power. For ultra-low power mode, the control pin voltage must be below 1.6V. Then the main oscillator is also turned off and the converter draws only 20µA from the input. Start-up will be slower from deep sleep than from standby.
    Negative control logic means that logic 0 (low) enables the converter and logic 1 (high) disables the converter. If the pin is left unconnected, it will be logic 0 and the converter will start up as soon as power is applied.
    Positive control logic means that logic 0 (low) disables the converter and logic 1 (high) enables the converter. If the pin is left unconnected, it will be logic 0 and the converter will not start up when power is applied, but wait for a positive signal before starting. For many safety-critical systems, this is an important feature.
    Quiescent or standby current is the current drawn by the converter from the supply when it is unloaded (the converter is active and has an output voltage, but no output current). The shutdown current is the residual current drawn by the converter from the supply while it is disabled by using the control pin. The control pin current is the current drawn by converter through the control pin in order to keep it in the disabled state.
    The maximum allowed control pin voltage varies from converter series to converter series. Most DC/DC converters allow up to 5V and some up to 12V or more. Refer to the datasheets for guidance. Do not connect an unused control pin to +Vin unless this is expressly permitted in the datasheet.
    All RECOM products will not be damaged if used without s load, although in some families some specifications may be out of range below 10% load.
    Nickel plated copper or aircraft-grade aluminium, depending on the converter series.
    We use a number of tin whisker mitigation strategies, all following the Jedec JP002 guidelines:

    Through Hole Devices
    The pins used in all of our through-hole converters are made of hard silver-copper alloy. The pins are then Nickel underplated to 0.5µm before being pure tin electroplated to 6µm thickness. This thickness of overplating is a compromise between reasonable manufacturing costs and having a thick enough coating to impair tin whisker formation. The surface is not ‘brightened’, also to mitigate tin whisker formation. Finally the pins are annealed according to JIS C3101. This reduces any residual forming stresses, which is one of the other potential causes of tin whisker formation.

    Surface Mount Devices:
    The carrier frames used in our SMD converters are made from DF42N nickel alloy which is pure tin plated. The pins are then hot dipped in Sn-Ag-Cu solder to mitigate tin whisker formation.
    The converters are not vacuum potted because we use a special process to remove the air bubbles (voids). The epoxy potting process is as follows:
    1- The two-component epoxy is mixed and placed under a vacuum for 1 minute to remove any air bubbles created by the mixing process.
    2- The plastic case is 1/3 filled and allowed to rest.
    3- The pre-tested converter pcb is inserted into the case and 2/3 filled and allowed to rest.
    4- The part completed converters are placed in a warm oven (30°C) for 20 minutes to allow any air bubbles to rise to the top.
    5- The case is sealed with a harder grade of epoxy and baked at 50°C for one hour to cure.
    6- In addition, spot checks are made with our X-ray machine to monitor and ensure that air voids are not present in any of our converters.
    The silicone rubber potting process is as follows:
    1- The pre-mixed silicone rubber compound is injected into the case
    2- The case is placed on to a shaker and vibrated to encourage any air bubbles to rise to the surface
    3- The case is topped up to the fill level
    4- The converters are put aside to cure at room temperature.
    An unregulated converter is a cheaper solution but offers less output voltage stability. The output voltage can change depending on both the load and the input voltage variations. Therefore, the input voltage range is restricted to +/-5% or +/-10% , so it is recommended to use unregulated DC/DC cpnverters only with a regulated supply voltage. The output voltage can rise substantially during no-load conditions, but, even an unregulated converter offers a low output voltage variation over a 20% to 100% load range.

    Regulated converters offer a much better load and line voltage regulation, typically less than 1%, so the output voltage is not dependant on the load or input voltage. In particular, the output voltage remains stable under low load or no load conditions. In addition, the input voltage range is higher (2:1, 4:1 or up to 7:1 with non-isolated converters), so regulated converters are suitable for use with variable input voltage supplies such a batteries or multiple supply voltages (e.g, 12V or 24V supplies)
    The current drawn by the converter when it is idle (not loaded). All converters contain oscillators that absorb power even if no power is being drawn from the converter.
    At a certain ambient temperature the internal heat dissipation makes it impossible for the converter to supply 100% of its power and the load must be derated (reduced) as the temperature goes higher. The derating curve shows the maximum power that the converter can deliver over the full operating temperature range. Some AC/DC converters allso have a low-temperature derating. This is due to increased losses caused by reduced efficiency at very low temperatures.
    Different converters have different on/off control voltages. Please check the datasheets carefully before connecting the on/off pin to ground or +Vin as this can damage the converter. Some on/off pins may require additional external components if driven with a TTL level signal.
    The higher power converters are optimized to run with the highest efficiency at full load. This means, for example, that the switching transistors need to switch very rapidly to avoid wasting power in the region between fully on and fully off. With no load, the switching drivers still run at full power which makes the converters run warm.
    Low power converters that uses post-regulation must be designed so that at the minimum input voltage there is enough output voltage headroom that the linear regulator can regulate properly. This means that with the nominal input voltage, there will be a higher voltage drop across the linear regulator, which in turn will increase the quiescent current drawn by the converter.

    Higher power converters often use synchronous rectification on the output. The switching transistors still run at full power even under no-load conditions, so this can lead to a high quiescent current.
    Yes, if they are derated (not used at full power). However, the simpler low cost converters have no overtemperature protection. If they are used outside of the temperature specification for a long period of time, they may fail. Our higher power DC/DC and AC/DC converters are fitted with over temperature protection. If they overheat they will simply shut down.
    We use standard coated wire with both converters because the windings are physically separated (reinforced isolation). For the RP-xxxx series the primary and the secondary are separated by a chamber system. The RxxP(2)xx series uses a two chamber system which primary and secondary windings are separated by an insulated bridge on both sides of the toroidal transformer.
    The isolation is tested with the inputs shorted together and the outputs shorted together and then the test voltage is applied between the input and output side. In this way the insulation is tested for all possible pathways between input and output, so the value applies equally for the low side and high side input.
    Isolation refers to the electrical separation (galvanic isolation) between the input and the output of the converter. This means that the output of an isolated converter is not linked to the input and any electrical interference, voltage differences and fault currents are blocked. This is extremely important in applications where the output circuit is connected to the “real” world and the main circuit must be separated from anything that happens to the output circuit. DC/DC converters are usually specified with the DC isolation for 1 second, AC/DC converters are usually specified with the AC isolation for 1 minute.
    The isolation voltage given in the datasheets is valid for 1 second flash test only. If an isolation barrier is required for longer or infinite time the Rated Working Voltage has to be used. Recom provides an isolation conversion calculator on the website to indicate the equivalence bewtween DC and AC isolation for 1s, 60s or continuous.
    It is very important that you compare the same type of isolation when comparing our products with the competitors to avoid misunderstandings.
    The PWM-control pin can be used as remote control pin as well. It means you can switch the unit on/off via this pin. Switching level is TTL compatible and has hysteresis to allow slow switching waveforms.
    Yes, our RACVxx series offer constant voltage outputs. The difference between a lighting CV driver and an industrial CV power supply is that the RACV's have full LED lighting certifications. (note: industial power supplies need PFC only above 75W. LED lighting regulations specify PFC from 25W. It is not permitted to use non-PFC power supplies above 25W)
    Yes, for our AC input drivers we offer 0-10V analog dimming, TRIAC dimming and Thermal dimming.
    The analog voltage is used to control an internal PWM circuit.
    The controller chip has a multi-stage shutdown:
    On : Open or 0V < Vr < 0.6V
    minimum quiescent current - all circuits shut down - slowest restart response time
    Off (Standby) : 0.6V < Vr < 2.9V
    output power stage and PWM oscillator off - medium restart response time
    Off (Shutdown) : 2.9V < Vr < 6V
    output power stage off, all other circuits active - quickest restart response time
    The RCD-24 series is step-down (buck) converter. You always need a higher input voltage than the output voltage required. A high power LED usually has a forward voltage drop of around 3.4V, so only three LEDs can be drivenin series from a 12V source. If the input voltage is increased to 24V, seven LEDs can be in the chain and if the input voltage is 36V, then ten LEDs can be driven.
    However, it is possible to connect chains of LEDs in parallel, so a RCD-24-7.0 can drive two chains of three 350mA LEDs connected in parallel.
    Remember that this part is a constant current converter, so the output voltage is variable depending on the power needed, but it will always be lower than the input voltage.
    The RCD series is a All-in-One solution in a small package with high efficiency, wide input range, two different ways of dimming Analog and Digital (PWM), high operating temperature range, and it’s fully tested. You don’t have to worry about all different suppliers of all the components of your discrete solution.
    The linearity outside the 10~90% range of the PWM dimming is not perfect, but still pretty good. The Analog dimming can be used in a 0~100% range.
    The inverse of MTBF (1/MTBF) gives FIT (Failures in Time) - the number of expected random failures per billion hours of operation.
    MTBF is calculated according to component reliability figures listed in the MIL STD 217F Handbook under Ground Benign (GB) environmental conditions.
    An alternate method is to use the figures listed by Bellcore TR-NWT-000332.
    The two methods are not comparable and give completely different results.
    The MTBF (Mean Time Between Failures) is a calculated figure based on the chances of a random failure causing the converter to stop working - ignoring all of the real-life stress factors such as over voltage stress, under voltage stress, thermal stress, switching stress or component aging. It should not be confused with operational lifetime. For comparison, the MTBF of a 25-year old healthy person is around 800 years - meaning if that person never got ill, lived an ideal, unstressed lifestyle and never aged - so that the only cause of death would be accidental injury- then that person would theoretically live 8 centuries. MTBF is a comparative measure of reliabilty, but not an absolute measure.
    The standard environment for MIL STD 217F calculations is Ground Benign.
    The correction factors for other environments are:

    Ground Benign (GB) = 1.00
    Ground Mobile (GM) = 0.61

    MTBF (Mean Time Between Failures) of different components in a system can be added up to give overall board-level reliability. As MTBF is a standard measure used for all electronic components, it is useful to also have the figure for the DC/DC converter in the datasheets.
    MTBF figures can also be used to compare the reliability of two different DC/DC products. The product with the highest MTBF will, in general, have the highest reliability. Care must be taken when comparing MTBF figures between different manufacturers as the way they are calculated may differ significantly.
    The absolute maximum voltage accepted in that pin is 15V, although its not recommended to go higher than 5V. You cant connect the input directly to the control pin
    The enable pin has two functions: Below 2.6V, the converter is OFF (the output power stage is switched off, but the converter oscillator is still running). Below 1.6V, the converter is in ultra-low power mode ( 20µA shutdown mode)
    The enable pin on the ROF-78 has a max voltage of 5VDC.
    1.25V is the threshold voltage, below that voltage the converter should be OFF. Above 1.25 the converter will be ON. The 0.9V and 1.55V values are recommended safety values to ensure that below 0.9 it will be OFF, and 1.55V it will be ON.
    In short, if you want to ensure that the device is on continuously, apply >1.55V to the EN pin all the time
    It is recommended that the R-78 series of switching converters is used with a minimum load of 6mA to guarantee that the output is stable under all operating conditions.
    As long as the output current is below the preset value the LED driver operates in CV (constant voltage mode). When the output current is lower than the preset current the drivers switches to CC (constant current) mode.
    The RAC04 family already works at -40degC (extended temperature), so it doesnt need the additional suffix (-E).
    Yes you can. Please refer to the Innoline Application Notes and find our recommended circuits to get a negative output from each series of our switching regulator families.
    The datasheets specify the maximum capacitive load. If the combined capacitive load is higher, the converter may go into short circuit protection on power-up.
    For switching regulators, but the output capacitor may discharge back into the output of the converter if the input supply is suddenly removed and damage the converter. Fitting protection diodes can avoid this reverse current flow.
    No. Switching regulators function differently than linear regulators and this “trick” does not work. They need a very good ground connection to function properly.
    All of our DC/DC converters contain a built-in input capacitor filter, so an external capacitor is not required for normal operation, unless specified in the datasheet. An input capacitor may also be required to meet surge requirements or to smooth the DC supply at the point of load. If several DC/DCs are powered from the same rail, then input capacitors placed close to the input pins are recommended.
    No external components are needed. An input capacitor is recommended only if the input voltage exceeds 26V. An output capacitor helps reduce output ripple further, but the ripple is relatively low anyway.
    The Innoline series all use intelligent controllers that measure the output current on each switching cycle (Current Mode Control). If the output is overloaded, the converter will deliver the over-current until either the converter overheats and shuts itself down (thermal protection) or the load current exceeds the safe limits. If the output is short circuited, the controller shuts down the output drive circuitry. The output condition is continuously monitored and the converter automatically restarts.
    Type is not critical. Actually, a lower quality, relatively high ESR capacitor on the input is actually an advantage as its internal resistance helps damp down any switch-on surge oscillations.
    A combination of tantalum or electrolytic in parallel with an MLCC on the input or output combines the advantages of both types (high ESR to reduce ringing, low ESR to filter noise).
    The R-78 costs more than a linear regulator because it is intelligent. It may look similar to a three-pin linear regulator, but it is far more efficient and inside is a controller chip that protects the converter against overload, over temperature and short circuits. This makes it very robust and hard-to-kill.
    Even if the converter itself costs more, the savings that can be made in the primary power supply (because it needs less output current), assembly (because there is no fiddly heatsink, screw, nut and thermal paste to worry about) and inventory (one part rather than 7 parts with the linear regulator + heatsink + mounting + input and output capacitors) mean that the overall power supply cost can be lower with the R-78 than with the ""cheaper"" linear regulator.
    A single-wire communications protocol. Data and addressing can be sent by different timings of the pulses on the wire. Return path is via a common ground connection.
    A two-wire communication protocol, e.g. 4-20mA Loop. Analog measurements are sent by modulating the current in an isolated 2-wire loop.

The digital I²C protocol also uses 2-wire communication, but is arranged as clock (SCL) and serial data (SDA) with a common ground.
    In a three-phase power supply system, three live conductors each carry an alternating current of the same frequency and voltage but each with a phase difference of one third of the period (120°). A return (neutral) conductor is not necessary as return currents cancel if the load is equally shared among the phases. Earth is a common reference but no current flows in it.

    Root Mean Square value of a waveform is the equivalent DC value that would deliver the same power to a given load (the average value of a 50/60Hz sine wave is zero as positive and negative half-cycles cancel out, so RMS must be used instead). For example, 115VAC is the RMS value of the US mains supply. The peak voltage is actually ≈163V.
    The term serial interface is often used for an RS-232 interface, consisting of Tx, Rx and ground wires, plus optional RTS and DSR handshaking lines. However, there are other serial interfaces in addition to RS-232 (e.g. RS-422)
    RS-485 and RS-422 are serial interface standards in which data is sent in a differential pair (two wires, or twisted pair cable), which allows greater distances and higher data rates than RS-232.
    Real-Time Clock: An Integrated circuit that contains a timer that supplies the time/date, usually powered by a long-life battery to allow it to keep track of time even when there is no system power applied.
    Siemens, the standard unit for conductance (the inverse of resistance). Siemens is used for singular and plural. Lower case s is the standard abbreviation for seconds.
    Surface Acoustic Wave: A sound wave that propagates along a hard surface. Used to make touchscreens by timing when and where a finger stops the wave.
    Also known as Euro-connector, a 21-pin connector commonly used in Europe to interconnect satellite receivers, television sets, and other AV equipment. Sometimes needs a DC/DC converter to supply a 10-12V ‘Device present’ signal.
    A 'Schottky-barrier junction' is a metal-semiconductor junction, rather than the P-N junction used in conventional semiconductor diodes. Schottky diodes are often chosen for their high switching speed and low forward voltage drop, (around 0.3V, compared to a standard diode’s typical 0.7V).
    Silicon-Controlled Rectifier: A semiconductor switch that once activated by a gate voltage, stays on until the input voltage turns off or reverses and therefore can be used as a latch. Typical uses include fault protection (OVP, OTP) which forces the user to turn off the device to reset the SCR.
    Secure Digital, a media format for non-volatile external memory cards. SD memories typically operate from 3.3V supplies and are best known as storage for digital cameras, smart phones, and other consumer electronic devices.
    A resistor placed in a current path to allow the current to be measured. The voltage across the sense resistor is proportional to the current that is being measured. Typical value is in milliohms. A Kelvin shunt has separate current and voltage connections to increase the measurement accuracy.
    Single Ended Primary Inductor Converter: A non-inverting, non-isolated DC-DC converter topology that acts both as a boost and a buck converter, that is, the output voltage can be higher or lower than the input voltage.
    A control pin typically used for sequencing of the turn-on or turn-off of a power converter with other converters.
    A digital interface in which data is sent in a single stream of bits, usually on a single wire-plus-ground, wire-pair, or single wireless channel (or two sets, one for each direction). Examples include USB, RS-232 and I2C
    In one ‘leg’ of bridge power converter topologies, one transistor ‘pushes’ current to the output to drive it toward a positive voltage; a second device ‘pulls’ current down to 0V. The transistor drivers are designed so both devices should never be on at the same time, which would effectively short the power supply. However, unintentional timing delays can sometimes cause both to be on simultaneously and the transient, high current that occurs while both devices are on is called shoot-through current.
    The ratio of the amplitude of a desired signal to the amplitude of superimposed noise signals. Usually expressed in decibels, dB. The larger the number, the better for data or signal quality
    Subscriber Identity Module: A SIM card identifies your cellphone so the system knows which phone should ring when someone calls your number.
    A topology where only one end of a transformer primary winding is switched, the other end being permanently connected to a DC bus voltage. Used in both DC/DC and AC/DC converters.
    A sensor that processes the raw measurement data and only sends relevant updates to reduce the amount of data traffic. Important for the concept of IoT if billions of devices are to be networked.
    System Management Bus: A 2-wire serial-interface standard similar to I²C, but with a faster clock speed.
    Surface Mount Device: An electronic component that mounts on the surface of a printed circuit board (as opposed to 'through-hole' or THT components which have pins or leads that are inserted into holes).
    Switch-Mode Power Supply. Much more efficient than ’linear’ power supplies, so almost exclusively used for power conversion above a few watts (with the exception of powering broadband RF amplifiers where the switching harmonics can cause interference).
    Surface Mount Technology
    A device which suppresses voltage transients and spikes. Usually a capacitor and resistor in series but can be more complex for lower losses.
    A feature in some switching power converters that limits the startup inrush current and sometimes output slew rate, at initial switch-on.

    Single-Pole/Single-Throw switch.
    Static RAM: Random Access Memory that does not require a clock to retain its data.
    Soft-start: Typically a pin on an IC to which a capacitor can be connected to set the start-up timing of a power converter to reduce the inrush current and/or output slew rate.

    A switch-mode voltage regulator in which output voltage is higher than its input voltage (boost converter).
    Power converter topology with a switching transistor and an inductive or sometimes capacitive energy storage element.
    A voltage regulator that uses a switching element to transform the supply into an alternating current, which is then converted to a different voltage using capacitors, inductors, and other elements, then converted back to DC. The switching regulator term often refers to an non-isolated converter.
    A technique used in switch-mode power supplies, in which the output rectifier diode is replaced with a MOSFET switch to reduce losses and thereby increase efficiency. The MOSFET is turned synchronously on and off with the main switch(es) to reproduce the effect of a diode.
    A System on a Chip (SoC) integrates most of a system's elements on a single integrated circuit (chip). It typically combines a microprocessor core along with interface elements and analog and mixed signal functions.
    A tap is an additional connection to a transformer winding besides the ends. The most common arrangements are the centre-tap in the middle of the winding and asymmetric taps used to make a 50/60Hz transformer primary compatible with 100 V, 115 V, 120 or 230/240 VAC supplies by connecting to the appropriate tap.
    Abbreviation for case temperature. The hottest case point and the maximum allowable operating temperature must be marked on all LED lighting AC/DC drivers.
    Transmission Control Protocol/Internet Protocol: The protocols or conventions that computers use to communicate over the Internet.
    A Thermo Electric Cooler is a small cooling device that relies on a semiconductor Peltier effect junction. Composed of two semiconductors made of different materials, a Peltier junction acts as a heat pump which can cool or warm when current is passed through it.

    Total Harmonic Distortion: A measure of signal distortion which assesses the energy in harmonics in a distorted signal compared with an original signal.
    An indication of power reduction required by changed ambient temperature. At higher ambient temperatures the headroom to the internal temperature limits in a power converter will decrease. Above a certain temperature, a load reduction is required to reduce internal losses and for internal heat dissipation to stay below acceptable limits. Some power converters also require power derating at low temperatures to ensure start-up.
    The use of various cooling methods, such as heatsinks, thermal interface materials (TIM) or fans to control temperature of power converters and their internal components.
    Deactivation of a circuit when a measured temperature exceeds a predetermined value. Can be latch-off or auto-reset upon cooling down. The reset temperature is typically lower than the trip temperature, exhibiting hysteresis.
    A resistor with a high temperature coefficient. As a negative temperature thermistor, it can be used as a series inrush current limiter (high resistance when cold, low resistance when hot).
    A temperature sensor formed by the junction of two dissimilar metals. A thermocouple produces a voltage proportional to the difference in temperature between the hot junction and the lead wire (cold) junction.
    A three-state output has three electrical states: One, zero, and ‘Hi-Z’, or open’. ‘Tri-State’ is a registered trade mark.
    A method for mounting components on a printed circuit board (PCB) in which pins or leads of the component are inserted into holes in the board and soldered in place.
    Through-Hole Technology
    Tin whiskers (also called Sn whiskers or metal whiskers) are microscopic, conductive, hair-like crystals that emanate spontaneously from pure tin surfaces and can cause short circuits and malfunction. There are various whisker mitigation processes that can be applied to reduce this effect, such as matt finishes, under-plating or over-plating.
    A standard logic gate output structure, originally implemented with bipolar transistors, but now typically in CMOS, where a P-channel MOSFET is connected in series with an N-Channel MOSFET and the connection point between the two is the output. The P-FET sits on top of the N-FET like a ‘totem pole’. This creates a push-pull output using just two transistors.
    Thin version of the QFN package (the JEDEC 'W' option) 0.8mm thick.
    Thin Quad Flat Pack
    An amplifier that converts a voltage to a current. Also known by several other terms, such as OTA, or Operational Transconductance Amplifier. The term derives from ‘transfer conductance’ and is measured in siemens (S), where 1 siemens = 1 ampere per volt. It is represented by the symbol gm. The basic gain of vacuum tubes and FETs is expressed as transconductance. Siemens is used for singular and plural of the unit.
    An inductive electrical device for changing the voltage of alternating current, consisting of two magnetically coupled coils. Alternating current in one (called the ‘primary’) creates a changing magnetic field which induces a current in the second coil (the ‘secondary’). Multiple secondary coils can be energised from a single primary winding. There is no such thing as a DC transformer, so an isolated DC/DC converter has to convert the DC input to an AC signal for the transformer primary and then rectify the resulting AC on the transformer secondary to a DC output.
    AC/DC power supplies that are non-isolated and use switched capacitors, high voltage regulators or switching converters to generate a low voltage DC output which is directly referenced to the AC input. These may only be used where human access to the secondary connections is prevented.
    See Dynamic Regulation.
    A basic term for a solid-state control device which allows or disallows current flow between two terminals, based on the voltage or current delivered to a third terminal.
    An ISO Technical Specification that aligns various automotive quality systems standards within the global automotive industry. Together with ISO 9001:2000, ISO/TS 16949:2002 specifies the quality system requirements for the design/development, production, installation and servicing of automotive related products. RECOM’s factories in Taiwan are ISO/TS 16949 certified.
    Thin Small-Outline Package
    Transistor-Transistor Logic: Logic gates implemented with bipolar transistor technology requiring a 5V±0.25V supply. Now almost universally superseded by CMOS logic.
    Transient Voltage Suppressor: A semiconductor device designed to protect a circuit from voltage transients. Typically implemented as a large silicon diode operating in avalanche mode to absorb large energy pulses quickly when the avalanche voltage is exceeded.
    A power converter topology that uses two transistors to switch each end of a transformer primary winding separately. Can be used with forward, flyback and tapped transformers.
    Transmit
    Microampere, or microamp: A millionth of an ampere. Ampere is the basic unit of electrical current.Often written as uA, but the u is a plain-text substitute for the Greek letter mu.
    Universal Asynchronous Receiver-Transmitter: An IC that converts parallel data to serial and converts received serial data to parallel data.
    A device that maintains AC power in the event of a mains failure. A UPS commonly includes a battery that is kept charged. When power fails, the battery powers an AC inverter to maintain the mains voltage for a duration defined by the capacity of the battery. This allows an orderly power-down of the system or to bridge short power outages. An off-line UPS connects the inverter only when power fails and may exhibit a short power interruption on changeover when mains fails. An on-line UPS routes power through the inverter permanently and shows no interruption on mains failure at the expense of lower operating efficiency. An on-line UPS also inherently provides protection against mains spikes and surges.
    Uniform Resource Locator: A web address.
    Universal Serial Bus (USB): A standard port that enables the connection of external devices to computers. The USB standard supports both data and power transfer. The new USB ‘Type C’ connector standard allows for 5V @ 3A (15W) up to 20V @ 5A (100W), as well as faster data transfer rates.
    Ultraviolet: The part of the electromagnetic spectrum just higher in frequency than visible light.
    Under-Voltage Lockout: A mechanism in a power converter to prevent operation if the input voltage is below a specified threshold.
    Peak-to-peak voltage.
    Volt-Ampere(s): If voltage and current are not in phase because a load has an inductive or capacitive element, then the power is measured in VA and not watts. This is because the product of the voltage and current values in a reactive circuit is higher than the power consumed. That is, real power consumed does not equal volts x amps.
    The supply voltage for a circuit is often given as V plus a double-letter suffix. The double letter is usually related to the lead of the transistors that are commonly connected to that supply, e.g. VCC is a positive-voltage supply and connects to the Collector terminal of bipolar transistors. VSS connects to the Source terminal of a FET, etc. V+ and V- are also used.
    Voltage-Controlled Oscillator: An oscillator device in which output frequency is proportional to a control voltage.
    Voice over Internet Protocol: A method for transmission of telephone calls over the Internet, e.g. Skype.
    Unit of measure for electromotive force (EMF), the electrical potential between two points. An electrical potential of 1 volt will push 1 ampere of current through a 1 ohm resistive load.
    A capacitor charge pump circuit which produces an output voltage which is twice the input voltage. A low cost, low power, non-isolated DC/DC converter.
    A circuit which is connected between a power source and a load, which provides a constant voltage despite variations in input voltage or output load. Voltage regulator is a generic term but is normally taken to imply non-isolated.
    A method of regulating a power converter output by sensing output voltage alone. See current mode control.
    Voltage Regulator Module. Another name for a switching regulators normally non-isolated DC/DC.
    Watt (W) is the unit of power. One watt is one joule of energy transferred or dissipated in one second. Electrical power is calculated as: watts = volts x amps x Power Factor Power factor can be disregarded for DC circuits or for AC circuits with a resistive load (it is unity in those situations).
    Semiconductor manufacturing begins with a thin disk of semiconductor material, called a ‘wafer’. A series of processes defines transistors and other structures, interconnected by conductors to build the desired circuit. The wafer is then sliced into 'die' which are mounted in packages, creating the semiconductor device.
    Wide Area Network: Any Internet or network that covers an area larger than a single building.
    Worldwide Interoperability for Microwave Access, a broadband, wireless access defined by the IEEE 802.16 standards. Wi-Fi (802.11) covers a small area with a radius of a few hundred meters, but WiMax (802.16) can cover up to 6 miles with only one base station.
    Circuits that transfer power using radio or inductive or capacitive coupling. Protocols include Qi, commonly used in mobile phone charging pads.
    Wireless Local Area Network
    X-Capacitors are certified for use across AC mains inputs. Y-capacitors are certified for use between AC mains and ground or in limited situations, across an isolation barrier. They are designed to self-repair after an over-voltage condition (self-healing). Y-capacitors have extra insulation as they must have at minimum ‘basic’ insulation, so are more expensive and only available in low capacitance values. Y capacitors pass leakage current so must not exceed prescribed capacitance values.
    Zero Current Switching: a mode of switch operation where it only operates when the current through the switch is zero, for minimum losses.
    A diode manufactured to have a specific reverse-breakdown voltage. Its most common use is as a voltage reference.
    Zero Insertion Force (socket): A class of IC sockets which clamp the IC pins after insertion (via a small lever on the side of the socket), and require no downward force on the IC or its pins to insert it into the socket.
    A standard for short-distance, low-data-rate, mesh (not point-to-point) communications. Created and maintained by the ZIGBEE Alliance Group.
    Zero Voltage Switching: a mode of switch operation where it only operates when the applied voltage is zero, for minimum losses.
    Prefix that is used with many inanimate things (homes, offices, phones, cities) to mean some sort of embedded intelligence and interconnectability.
