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 discrete MOSFET and controller or RCC 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.
