The is a high-performance, off-line switching regulator integrated circuit (IC) manufactured by Sanken Electric Co., Ltd. , designed specifically for Switched-Mode Power Supplies (SMPS) . By combining a high-voltage power MOSFET and a current-mode PWM controller into a single 5-pin SIP/TO-3P package , this IC minimizes external component count, increases power efficiency up to 95%, and lowers electromagnetic interference (EMI). It is widely used across consumer electronics, including legacy Sony CRT televisions, power adapters, and industrial electronics.

By integrating the controller block alongside a rugged power MOSFET on the same silicon substrate, the IC eliminates complex discrete snubber networks and external gate drive paths. This reduces the total bill of materials (BOM), minimizes electromagnetic interference (EMI) radiation loops, and guarantees system efficiency under varying load conditions.
