Description

The Fairchild Power Switch(FPS) product family KA5Q is specially designed for an off-line SMPS with minimal external components. The Fairchild Power Switch(FPS) KA5Q consist of high voltage power SenseFET and current mode PWM controller IC. PWM controller KA5Q 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) KA5Q can reduce total component count, design size, and weight and at the same time increase & efficiency, productivity, and system reliability. KA5Q has a basic platform well suited for cost-effective design in quasi resonant converter as C-TV power supply.
