Design Tools

- Adjustable switching frequency from 100 kHz to 2 MHz

- Fixed soft start and selectable preset 100 %, 75 %, and

50 % current limit

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

please see www.vishay.com/doc?99912

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

• Industrial and server computing

• Networking, telecom, and base station power supplies

• Wall transformer regulation

• Robotics

• High end hobby electronics: remote control cars, planes,

and drones

• Battery management systems

• Power tools

• Vending, ATM, and slot machines

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

enhanced PowerPAK^®MLP54-A6C package in

mm x 6.5 mm x 3 mm dimensions.
