Notes:
1. Tj = 25°C to 150°C
2. Repetitive rating: Pulse width limited by maximum junction temperature
3. L = 80mH, VDD = 50V, RG = 27, starting Tj = 25°CDescriptiondesigned for an off line SMPS with minimal external components. The Fairchild Power Switch(FPS) KA1H0165RN 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 rotection, 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 The Fairchild Power Switch(FPS) KA1H0165RN can reduce total component count, design size, weight and at the same time increase & efficiency, productivity, and system reliability. The KA1H0165RN has a basic platform well suited for cost effective design in either a flyback converter or a forward converter.
