Description
The FSDM07652R 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 simulta-
neously increasing efficiency, productivity, and system
reliability. This device is a basic platform well suited for cost
effective designs of flyback converters.
