Fairchild Power Switch(FPS)
Features
Description
• Quasi Resonant Converter Controller
• Internal Burst mode Controller for Stand-by mode
• Pulse by pulse current limiting
• Over current Latch protection
• Over voltage protection (Vsync: Min. 11V)
• Internal thermal shutdown function
• Under voltage lockout
The 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 contorller IC.
PWM controller features integrated fixed oscillator, under
voltage lock out, leading edge blanking, optimized gate turn-on/
turn-off driver, thermal shut down protection, over voltage
protection, temperature compensated precision current sources
for loop compensation and fault protection circuit. compared to
• Internal high voltage sense FET
• Auto-restart mode
discrete MOSFET and controller or R
CC
switching converter
solution, a Fairchild Power Switch(FPS) can reduce total
component count, design size, and weight and at the same time
increase & efficiency, productivity, and system reliability. It has
a basic platform well suited for cost-effective design in
quasi resonant converter as C-TV power supply.
