SiC438 Overview
The SiC43x are synchronous buck regulators with integrated high side and low side power MOSFETs. Its power stage is capable of supplying 12 A (SiC437) and 8 A (SiC438) continuous current at up to 1 MHz switching frequency. This regulator produces an adjustable output voltage down to 0.6 V from 3 V to 28 V input rail to acmodate a variety of applications, including puting, consumer electronics, tele, and industrial.
