• Internet of Things

    The Internet of Things (IoT) is an umbrella term that covers many groups of related concepts, but in essence, these concepts share the following features: distributed intelligence, multiple interconnected sensors/actuators and decentralized control. In practice, IoT means that certain spaces, environments or objects can be made “smart” by incorporating sensors that can communicate to make them behave intelligently. IoT examples include offices that adjust themselves to ambient light levels or to human presence, machines that monitor their own health or homes that learn our daily routines to automatically save energy without compromising on our comfort.

    All of this new technology needs power: either highly efficient, low standby consumption AC/DC power supplies that can be used in a smart office with hundreds of intelligent sensor nodes, energy harvesting solutions, or cost effective, space saving DC/DC power modules. Not every power supply is suitable for an Internet of Things application. They must be highly efficient at both low load and full load, they must be able to handle fast transient and dynamic load currents, they must be physically compact, they must be reliable and, above all, they must be affordable as they will be as ubiquitous as the sensors, processors, radios and actuators that they supply. This is why RECOM have developed next generation 3DPP® DC/DC power modules such as the RPMx, RPX or RPL– miniature low-profile SMD power supplies that can deliver up to 17W but fit into 1cm² or less board space or the RxxCTxx which delivers 5kVAC isolation in a 2.6mm high package.

    Easy fit AC/DC converter (5W)

    The RAC05-SK/C14 is as easy to mount as a mains filter, but is a fully fledged power supply. This unique design has an IEC mains input connector (commonly called a kettle plug) which accepts a universal 85VAC to 264VAC supply but delivers a safe, touchable, short circuit protected DC output of 3.3, 5, 12, 15 or 24VDC.

    The mounting hole is a standard die punch size, so fitting the power supply is quick and easy, requiring only two fixings. The 5W output is easily sufficient to power single board computers such as the Raspberry Pi, Arduino and BBC Micro:bit, as well as IoT nodes, sensors and relay stations. Typical industrial applications include IoT mesh networks, 19” rack mount equipment, short production runs or mass production.

    Low profile & cost effective DC/DC Converters

    Industry 4.0 will revolutionize smart manufacturing, creating smart factories that communicate with each other to speed up the manufacturing chain. As the number of sensors, actuators, drives and control nodes increase, it will become crucial that the interactions remain secure and reliable.

    Therefore, RECOM offers low profile & cost effective DC/DC converters for IoT applications as well as boost and buck switching regulator modules specially designed for very low power applications.

    Very low power switching regulators

    R-78S series

    The R-78S switching regulator has been specially designed for single-cell powered IoT applications. Due to their wide input voltage range, high efficiency and low stand-by losses, they extend not only the working lifetime of the cell, but also maintain a stable 3.3V output down to “the last gasp” battery voltage. Based on the simple plug-and-play concept of the standard R-78 buck regulator, the R-78S boost regulator is able to provide a stable 3.3VDC output from an input voltage down to 0.65V, allowing a single battery cell to power IoT nodes, Bluetooth-enabled sensors or long range LoRaWAN remote data transmitters.

    R-78S evaluation board allows battery calculations

    RECOM’s R-78S evaluation board allows engineers to effortlessly test the functionality of the R-78S switching regulator, which boosts a AA battery or external supply voltage to 3.3V for low power IoT applications. The evaluation board is equipped with several jumper headers to measure input and output current and voltage - allowing typical battery lifetime calculations in both active and standby mode.

    R-78S boosts a AA battery to continuous 3.3V for IoT

    The R-REF02-78S is a ready-to-use design for 3.3V IoT applications. It generates 3.3V from a single AA battery and can directly be used in any application. The reference design contains a AA battery holder and an R-78S3.3-0.1 boost converter. Two jumper headers J1 and J2 connect to the output voltage and the CTRL pin of the R-78S converter. An enable pin puts the R-78S into sleep-mode where it draws only 7uA from the battery.
