SIC9763D : 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. The SIC976XD are supplied from the main line, the VDD power supply resistors and power feedback circuits from LED chips are not needed, save cost and help for assemble efficiency. The SIC976X.
