The SiC931 is a synchronous buck regulator module with
integrated power MOSFETs and inductor. Its power stage
is capable of supplying 20 A continuous current at up to
2 MHz switching frequency. This regulator produces an
adjustable output voltage down to 0.6 V from 4.5 V to 18 V
input rail to accommodate a variety of applications,
including computing, consumer electronics, telecom, and
industrial.
SiC931’s architecture supports ultrafast transient response
with minimum output capacitance and tight ripple regulation
at very light load. The device is internally compensated and
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 integrates a full protection feature set,
including output over voltage protection (OVP), cycle by
cycle over current protection (OCP) short circuit protection
(SCP) and thermal shutdown (OTP). It also has UVLO and a …
