Product Summary

Description:The SPS product family is specially designed for an off-line  SMPS with minimal external components. The SPS 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 SPS 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
