Synchronous Buck Regulator EVB
The SiC967evb-A is the evalutation board for the SiC967, a synchronous buck regulator module with integrated power MOSFETs and inductor. Its power stage can supply 6 A continuous current at up to 2 MHz switching frequency. This regulator produces an adjustable output voltage down to 0.8 V from 4.5 V to 60 V input rail to accommodate a variety of applications, including computing, consumer electronics, telecom, and industrial.
SiC967’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 6 ms soft start. The SiC967 is available in lead (Pb)-free power enhanced PowerPAK® MLP10665-60L package in 10.6 mm x 6.5 mm = x 3mm dimensions.
