Description

PWM

The FSCM0765R is an integrated Pulse Width Modulator

(PWM) and SenseFET specifically designed for high

performance offline Switch Mode Power Supplies (SMPS)

with minimal external components. This device is an

integrated high voltage power switching regulator which

combines an avalanche rugged SenseFET with a current

mode PWM control block. The PWM controller includes

integrated fixed frequency oscillator, under voltage lockout,

leading edge blanking (LEB), optimized gate driver, internal

soft start, temperature compensated precise current sources

for a loop compensation, and self protection circuitry.

Compared with a discrete MOSFET and PWM controller

solution, it can reduce total cost, component count, size, and

weight while simultaneously increasing efficiency, productivity,

and system reliability. This device is a basic platform well

suited for cost effective designs of flyback converters.
