Fairchild Power Switch(FPS)
Features Precision fixed operating frequency (100/67/50kHz) Low start-up current(typ. 100uA) Pulse by pulse current limiting Over current protection Over voltage protecton (Min. 25V) Internal thermal shutdown function Under voltage lockout Internal high voltage sense FET Auto-restart mode
Applications SMPS for VCR, SVR, STB, DVD & DVCD SMPS for Printer, Facsimile & Scanner Adaptor for Camcorder
DescriptionThe Fairchild Power Switch(FPS) product family is specially
designed for an off-line SMPS with minimal external
components. The Fairchild Power Switch(FPS) consist of
high voltage power SenseFET and current mode PWM IC.
Included PWM controller features integrated fixed
frequency oscillator, under voltage lock-out, leading edge
blanking, optimized gate turn-on/turn-off driver, thermal
shutdown protection, over voltage protection, and
temperature compensated precision current sources for
loopcompensation and fault protection circuitry. compared
to discrete MOSFET and PWM controller or RCC solution, a
Fairchild Power Switch(FPS) can reduce total component
count, design size, weight and at the same time increase
efficiency, productivity, and system reliability. It has a basic
platform well suited for cost effective design in either a
flyback converter or a forward converter.
