KA1M0280RB/KA1H0280RB  
Fairchild Power Switch(FPS)  
Features  
Description  
• Precision Fixed Operating Frequency  
• KA1M0280RB (67kHz) , KA1H0280RB (100kHz)  
• Pulse by Pulse Over Current Limiting  
• Over Load Protection  
• Over Voltage Protection (Min. 23V)  
• 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  
discrete MOSFET and controller or R

switching converter  
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.
