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 controller 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.
