Features
Fairchild Power Switch(FPS)
Description
FS8S0765RCB 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.
