Description

The SPS product family KA3S0765RF is specially designed for an offline SMPS with minimal external components. The SPS KA3S0765RF consist of high voltage power SenseFET and current mode PWM IC. Included control IC KA3S0765RF features a trimmed oscillator, under voltage lock-out, leading edge blanking, optimized gate turnon/ 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 reliabilit. It has a basic platform well suited for cost-effective C-TV power supply.
