Description
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.
