Fairchild Power Switch(FPS)

Features

Description

• Burst Mode Operation to Reduce the Power Consumption

in the Standby Mode

FS8S0965RCB is a Fairchild Power Switch (FPS) that is

specially designed for off-line SMPS of CRT monitor with

minimal external components. This device is a current mode

PWM controller combined with a high voltage power

SenseFET in a single package. The PWM controller features

integrated oscillator to be synchronized with the external

sync signal, under voltage lockout, optimized gate driver and

temperature compensated precise current sources for the

loop compensation. This device also includes various fault

protection circuits such as over voltage protection, over load

protection, abnormal over current protection and over tem-

perature protection. Compared with discrete MOSFET and

PWM controller solution, FPS can reduce total cost, compo-

nent count, size and weight simultaneously increasing effi-

ciency, productivity and system reliability. This device is well

suited for the cost effective monitor power supply.
