SIC9753 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.
SIC9753 Key Features
- Active PFC for High power factor and low THD -No auxiliary winding -600V high voltage MOSFET integrated -±3% LED output
- System efficiency up to 95% -Ultra low start up & operating current -Cycle-by-cycle current limit -LED short protection
