SIC9753 SI Semiconductors High Precision Non-Isolated Buck APFC LED Driver

Description The SIC9752/SIC9753 are 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. Critical conduction mode operation reduces the switchi...
