Description
The FSDM0465RE, FSDM0565RE and FSDM07652RE
are 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.
