500765RT Datasheet – Fairchild Power Switch (FPS)
Fairchild Power Switch SMPS for Color Television
500765RT overview
The 500765RT is a Fairchild Power Switch SMPS for Color Television made by Fairchild Semiconductor, supplied in these packages: TO-220, TO-3P. The absolute maximum ratings table on this page lists the 14 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the 500765RT pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The Fairchild Power Switch(FPS) product family 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. PWM controller 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) can reduce total component count, design size, and weight and at the same time increase & efficiency, productivity, and system reliability. It has a basic platform well suited for cost-effective design in quasi resonant converter as C-TV power supply.
