Shenzhen SI Semiconductors Co., LTD. Main Line Power Up Non-Isolated Buck APFC LED Driver Product Specification SIC976XD General Description The SIC976XD are built-in HV start-up and IC power supply circuit, main line power up constant current LED regulators with high current accuracy which applies to single stage step-down power factor corrected LED drivers. 600V power MOSFET is integrated, which can significantly simplify the design of LED lighting system. High accuracy of output current is achieved by sampling the output current directly. Quasi Resonant (QR) Buck topology reduces the switching losses and largely increases the efficiency.
