Description

The FSDM311 is an integrated Pulse Width Modulator

(PWM) and Sense FET specially designed for high performance

off-line Switch Mode Power Supplies (SMPS) with

minimal external components. This device is a monolithic

high voltage power switching regulator which combines an

VDMOS Sense FET with a voltage mode PWM control

block. The integrated PWM controller features include: a

fixed oscillator, Under Voltage Lock Out (UVLO) protection,

Leading Edge Blanking (LEB), optimized gate turn-on/

turn-off driver, thermal shut down protection (TSD), temperature

compensated precision current sources for loop compensation

and fault protection circuitry. When compared to a

discrete MOSFET and controller or RCC switching converter

solution, the FSDM311 reduces total component

count, design size, weight and at the same time increases

efficiency, productivity, and system reliability. This device is

a basic platform well suited for cost effective designs of flyback

converters.
