DESCRIPTION
FEATURES
The JW1758A/B/C is a constant current LED controller with high current accuracy which applies to single stage step-down power factor corrected LED drivers. 600V power MOS is integrated, which can significantly simplify the design of LED lighting system. JW1758A/B/C integrates high voltage power source, and can be supplied by line voltage directly, and auxiliary winding is not needed. High accuracy of output current is achieved by sampling the output current directly. Critical conduction mode operation reduces the switching losses and largely increases the efficiency.
