Description
The FSFM260/261/300 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 discrete MOSFET and PWM controller
solutions, it can reduce total cost, component count, size,
and weight while simultaneously increasing efficiency,
productivity, and system reliability. This device is a basic
platform for cost-effective designs of flyback converters.
Applications
! Power Supply for LCD TV and Monitor, VCR, SVR,
STB, DVD, and DVD Recorder
! Adapter
