Description

The SPS product family KA2S0880 is specially designed for an off line SMPS with minimal external component. The SPS KA2S0880 consist of high voltage Power SenseFET and current mode PWM IC. Included control IC KA2S0880 features a tr-immed oscillator, under voltage lock out, leading edge blanking, optimized gate turnon/ turn-off driver, thermal shut down protection, over voltage protection, and temperature compensated precision current source for loop compensation and fault protection circuitry. 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. KA2S0880 has a basic platform well suited for cost effective monitor power supply.
