DESCRIPTION
- 3 modes of operation, forced continuous conduction,
power save or ultrasonic
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.
• Robust and reliable
- Output over voltage protection
- Output under voltage / short circuit protection with auto
retry
- Power good flag and over temperature protection
- Supported by Vishay PowerCAD online design
simulation
• High power density
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.
- Integration of high current output inductor
- 10.6 mm x 6.5 mm x 3 mm low profile MLP package
• Easy of use
- Internal compensation
- Low peripheral component count
• Material categorization: for definitions of compliance

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.
APPLICATIONS
• Industrial and automation
• Home automation
