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), this 5-pin hybrid IC integrates a robust power MOSFET and a current-mode PWM controller onto a single substrate. It is widely used in classic consumer electronics, including CRT televisions, VCRs, and audio amplifiers, because it reduces component counts and simplifies PCB layout.
