Description
The Fairchild Power Switch FS7M-series is an integrated
Pulse Width Modulator (PWM) and Sense FET 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 combine an avalanche rugged Sense FET
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,
soft start, temperature compensated precise current sources
for a loop compensation and self protection circuitry.
Compared with discrete MOSFET and PWM controller
solution, it can reduce total cost, component count, size and
weight simultaneously increasing efficiency, productivity, and
system reliability. This device is a basic platform well suited
for cost effective designs of flyback and forward converters.
