Product Summary
The 5q1265rf is a Fairchild Power Switch. The 5q1265rf 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. The 5q1265rf 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. The 5q1265rf has a basic platform well suited for cost-effective design in quasi resonant converter as C-TV power supply.
