Description

The SPS product family KA5M0765RC is specially designed for an off-line SMPS with minimal external components. The SPS KA5M0765RC consist of high voltage power SenseFET and current mode PWM IC.

Included PWM controller KA5M0765RC 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 compensated precision current sources for loop compensation and fault protection circuitry. Compared to discrete MOSFET and PWM controller or RCC solution, a SPS can reduce total component count, design size, weight and at the same time increase efficiency, productivity, and system reliability.

KA5M0765RC has a basic platform well suited for cost-effective design in either a flyback converter or a forward converter.
