Offline Buck Converter for the IoT Applications from Diodes

Diodes announced the AL17050 universal offline buck converter designed for low-power Internet-of-Things (IoT) applications. With its wide AC input voltage range and fully integrated MOSFET, it provides a compact and efficient solution to generating a constant voltage for low-power applications that need to comply with strict standby power restrictions.

The AL17050 has been developed to accept an AC input voltage between 85VAC and 265VAC, making it suitable for any region. The internal MOSFET is able to withstand voltages of up to 500V yet is optimized for low-power applications, meaning the device only consumes 100μA of static current. Furthermore, the device automatically adjusts to low loads, so it delivers excellent overall efficiency.

The non-isolated design minimizes the BoM for manufacturers developing applications for the IoT, such as smart appliances, smart sensors, and connected lighting. The AL17050 delivers a constant 3.3V/5V at up to 60mA, making it ideal for devices based on low power microcontrollers (MCUs) that integrated IoT connectivity such as Bluetooth® LE or Zigbee™ (more info).
