SiC437, SiC438
Vishay Siliconix
3 V to 28 V Input, 8 A, 12 A microBUCK® DC/DC Converter
DESCRIPTION
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 accommodate a variety of applications, including computing, consumer electronics, telecom, and industrial.
SiC437’s and SiC438’s architecture delivers ultrafast transient response with minimum output capacitance and tight ripple regulation at very light load. The device is internally compensated and is stable with any capacitor. No external ESR network is required for loop stability purposes. The device also incorporates a power saving scheme that significantly increases light load efficiency.
The regulator family integrates a full protection feature.
