AC/DC and DC/DC Conversion > DC/DC SMPS - Single Output SIC431AEVB-A: 1V, 3.3V, 5V or 12V @ 20A, 3V ~ 24V, Buck Manufacturer: Vishay Siliconix

The SiC431 is from a family of synchronous buck regulators with integrated high side and low side power MOSFETs. Its power stage is capable of supplying up to 24 A (Eval board = 20 A max) continuous current at 1 MHz switching frequency. This regulator produces an adjustable output voltage down to 0.6 V from 3 V to 24 V input rail to accommodate a variety of applications, including computing, consumer electronics, telecom, and industrial.

AC/DC and DC/DC Conversion > AC/DC SMPS - Single Output REF3WIOTCOOLSETTOBO1: 5 V, 3 W, 1 Isolated Output, Offline Flyback Power Supply Manufacturer: Infineon Technologies

In this application, an Infineon ICE3RBR4765JG from the CoolSET™ jitter series is used as a flyback controller. The controller has a built-in 650 V CoolMOS™ as the main switching component, as well as the startup cell. The reference design board operates in Discontinuous Conduction Mode (DCM), running at 65 kHz switching frequency.
