5M0765RC Datasheet | Fairchild Semiconductor

features integrated fixed frequency oscillator, under voltage lock-out, leading edge blanking, optimized gate turn-on/turn-off driver, thermal shutdown protection, over voltage protection, and temperature pensated precision current sources for loop pensation and fault protection circuitry. pared to discrete MOSFET and PWM controller or RCC solution, a SPS can reduce total ponent 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. TO -22 0F -5L 1. GND 2. Drain 3. Vcc 4.
