KA5Q1265RFH/KA5Q12656RTH  
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) consists of a  
high voltage power SenseFET and a current mode PWM IC.  
The integrated PWM controller includes the fixed oscillator,  
the under voltage lock out, the leading edge blanking, the  
optimized gate turn-on/turn-off driver, the thermal shut down  
protection, the over voltage protection, and the temperature  
compensated precision current sources for loop compensation  
and fault protection circuitry. Compared to a discrete  
MOSFET and a controller or a RCC switching converter  
solutions, a Fairchild Power Switch(FPS) can reduce the total  
number of components, design size, and weight, so it will  
improve efficiency, productivity, and system reliability. It has  
a basic platform well suited for cost-effective design in a  
quasi-resonant converter as a C-TV power supply.
