Description
The FSCM0465R 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 that combines an avalanche rugged
SenseFET with a current mode PWM control block. The
PWM controller includes an 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.
