Product Overview

The KA5M0365RTU is a 650V Integrated Power Switch for 35W offline flyback converters. 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 IC. Included PWM controller integrates the fixed frequency oscillator, the under-voltage lock-out, the leading edge blanking, the optimized gate turn-on/turn-off driver, the thermal shutdown protection, the overvoltage protection and the temperature compensated precision current sources for the loop compensation and the fault protection circuitry. Compared to discrete MOSFET and PWM controller or RCC 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.
  • Precision fixed operating frequency (100/67/50kHz)
  • Low start-up current (typical 100µA)
  • Pulse by pulse current limiting
  • Over-current protection
  • Overvoltage protection (Min. 25V)
  • Internal thermal shutdown function
  • Under-voltage lockout
  • Internal high voltage sense FET
  • Auto-restart mode
