Description
The FSDM0465RS is an integrated Pulse-Width
Modulator (PWM) and SenseFET specifically designed
for high-performance offline Switch Mode Power
Supplies (SMPS) with minimal external components.
The 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 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 reduces total cost, component count, size and
weight; while increasing efficiency, productivity and system
reliability. This device is a basic platform well suited for
cost effective designs of flyback converters.
