High Performance SMD-Power Modules

The RECOM RPH-3.0 is a 3A point of load buck converter in a compact 10 x 12 x 4mm QFN SMD package with a wide input voltage range from 4.5V to 55 V DC, allowing 12V, 24V, 36V and 48V batteries to be used. Following RECOM’s ‘Power Packaging’ concept, the shielded inductor is integrated, and the control IC is flip-chip mounted for outstanding electrical and thermal performance.

The output voltage can be set using two resistors in the range of 1V-15V, and a single resistor sets the operating frequency in the range of 100 – 1000kHz. Comprehensive functionality is provided with on/off control, a power good signal, soft-start and full protection against short circuits, over-voltage, over-temperature and overload. With derating, the part can operate reliably at ambient temperatures of up to 125°C.

RECOM’s new power modules RPX-1.0, RPX-1.5, RPX-2.5, and RPX-4.0 have high power density footprints using thermally-enhanced QFN packages (SMD) for an operating temperature up to at least 85°C without forced air cooling. The 1A and 1.5A versions in 3mm x 5mm x 1.6mm QFN packages accept an input voltage range up to 36VDC and down to 4 VDC, allowing 5V, 12V, 15V, or unregulated 24VDC supply voltages to be used. The output voltage can be set with two resistors in the range from 0.8VDC up to 30VDC. The RPY also has an input voltage range of 4 – 36VDC, but instead of a regulated output voltage offers a dimmable constant current output of up to 1.5A, making it ideal for driving light power LEDs.

The 2.5A version in a 4 x 4.5 x 2.0mm QFN package accepts an input voltage range up to 28VDC and down to 4.5VDC, allowing 5V, 12V, 15V, or 24VDC supply voltages to be used. The output voltage can be set with two resistors in the range from 1.2VDC up to 6VDC.

The input range for RPX-4.0 is from 3.8V to 36VDC, allowing 5V, 12V, or 24VDC supply voltages to be used. It also features a programmable output voltage from 1V to 7VDC. This tiny converter (5.0 x 5.5 x 4.1mm) with its incredible thermal management opens up new possibilities in industrial automation, portable devices, and high-density or weight-sensitive applications.

Products in the RPX series are complete power modules with integrated power transistors and inductors, requiring only input and output capacitors and voltage setting resistors to form fully functioning power regulators with short-circuit protection, over current limiting and thermal shutdown. A resistor divider on the input allows an under-voltage lockout voltage to be set to protect battery-powered supplies from over-discharge. A resistor divider on the output allows the output voltage to be set over a very wide range. An enable input permits voltage supply sequencing and low power consumption in shutdown (microamps). State-of-the-art integration and RECOM’s ‘3D Power Packaging’ technology deliver optimal thermal management and high power density while lowering manufacturing costs, giving you exceptional electrical and thermal performance at a very affordable price.

Some products in the RPX and the RPY QFN package DC/DC converter series are now also offered as -Q variants, qualified to automotive standard AEC-Q100 grade 1, for operation up to +125°C. These parts include ‘wettable’ flanks, which facilitate automated optical inspection of the land-grid array solder joints.

The RECOM RPL-1.0, RPL-3.0 and RPL-5.0 are 1 amp, 3 amp and 5A point of load buck converters in a tiny 3 x 3mm LGA SMD package. The input range of the RPL-1.0 is 3V to 22V and the RPL-3.0 is 4V to 18V, while the RPL-5.0 starts lower at 2.75V to 17V. The output voltage can be set using two resistors in the range of 0.6V to 12V (RPL-1.0 and RPL-5.0) or 0.8V to 5.2V (RPL-3.0).

The RECOM RPL-10 and RPL-20 are high current 10 amp and 20A_peak point of load buck converters in a compact 7 x 7mm LGA SMD package. The input range of the RPL-10 and RPL-20 is 4V to 16V, while the output voltage can be set using two resistors in the range of 0.6V to 5.5V.

Following RECOM’s ‘Power Packaging’ concept, the inductor is integrated and the control IC is embedded within the substrate for outstanding electrical and thermal performance. Only a few low-cost passive components are needed to create a fully functioning power supply. Comprehensive functionality is provided with output voltage sensing (3A and 5A), on/off control, a power good signal and full protection against short circuits, over-voltage, over-temperature and overload. With derating, the parts can operate reliably at ambient temperatures of up to 125°C.

RECOM RPZ modules are exceptional due to constant-on-time current control, giving an ultra-fast regulation of dynamic load transients.

RECOM’s new RPZ power modules RPZ-0.5, RPZ-1.0, RPZ-2.0, RPZ-3.0A and RPZ-6.0 have high power density footprints using thermally enhanced SMD packages for an operating temperature up to more than 100°C without forced air cooling. The innovative constant-on-time control loop eliminates the delay due to an internal compensation network and permits ultra-fast regulation of transient loads and conversion efficiencies up to 92%.

The 0.5A and 1A versions in 2mm x 2mm QFN packages accept an input voltage range from 2.3V up to 5.5V, allowing 3.3V or 5V fixed supply voltages or a single Li-ion cell to be used. The output voltage can be set with two resistors in the range from 0.6VDC up to 5.25VDC.

The 2A and 3A versions in 2.5mm x 3.5mm QFN packages accept an input voltage range from 2.75V up to 6V, allowing 3.3V or 5V fixed supply voltages or a single Li-ion cell to be used. The output voltage can be set with two resistors in the range from 0.6VDC up to 5.5VDC.

The 6A version in a 4 x 6mm QFN package accepts an input voltage range up to 7VDC and down to 2.75VDC, allowing 3.3V or 5V fixed supply voltages or a single Li-ion cell or a 6V battery to be used. The output voltage can be set with two resistors in the range from 0.6VDC up to 6.65VDC.

Products in the RPZ series are complete power modules with integrated power inductors, requiring only input and output capacitors and voltage setting resistors to form fully functioning power regulators with short-circuit protection, over current limiting and thermal shutdown. A resistor divider on the input allows an under-voltage lockout voltage to be set to protect battery-powered supplies from over-discharge. A resistor divider on the output allows the output voltage to be set over a very wide range. An enable input permits voltage supply sequencing and low power consumption in shutdown (microamps). State-of-the-art integration and RECOM’s ‘3D Power Packaging’ technology deliver optimal thermal management and high power density while lowering manufacturing costs, giving you exceptional electrical and thermal performance at a very affordable price.

The RPMH series delivers 0.5A or 1.5A with trimmable output voltages and an input voltage range from 5-60V for 1.5A and 4.3-65V for the 0.5V version making these modules perfect for systems operating on nominal 5, 12, 24 or 48V rails.
