DESCRIPTION
- Fixed soft start and selectable preset 100 %, 75 %, and 50 % current limit The SiC967 is a synchronous buck regulator module with - 3 modes of operation, forced continuous conduction, power save or ultrasonic integrated power MOSFETs and inductor. Its power stage is • Robust and reliable capable of supplying 6 A continuous current at up to 2 MHz - Output over voltage protection switching frequency. This regulator produces an adjustable - Output under voltage / short circuit protection with auto output voltage down to 0.8 V from 4.5 V to 60 V input retry - Power good flag and over temperature protection rail to accommodate a variety of applications, including - Supported by Vishay PowerCAD online design computing, consumer electronics, telecom, and industrial. simulation SiC967’s architecture supports ultrafast transient response • High power density - Integration of high current output inductor with minimum output capacitance and tight ripple regulation - 10.6 mm x 6.5 mm x 3 mm low profile MLP package at very light load. The device is internally compensated and • Easy of use no external ESR network is required for loop stability - Internal compensation purposes. The device also incorporates a power saving - Low peripheral component count • Material categorization: for definitions of compliance scheme that significantly increases light load efficiency. please see www.vishay.com/doc?99912 The regulator integrates a full protection feature set,
