DESCRIPTION

The SiC967 is a synchronous buck regulator module with

integrated power MOSFETs and inductor. Its power stage is

capable of supplying 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 a

user fixed 6 ms soft start.

The SiC967 is available in lead (Pb)-free power

enhanced PowerPAK? MLP54-A6L package in 10.6

mm x 6.5 mm x 3 mm dimensions.
