Description

The SPS product family KA2S0880B is specially designed for an off-line SMPS with minimal external components. The SPS KA2S0880B consist of high voltage power SenseFET and current mode PWM Controller IC. PWM controller KA2S0880B features integrated fixed oscillator, under voltage lockout, 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. KA2S0880B has a basic platform well suited for cost effective design in monitor power supply.
