Description
The FSDM0565RB 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, internal 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 converters.
