JW1769A/B/C Parameters Subject to Change Without Notice Offline Step-down LED Regulator With PFC and High Voltage MOSFET DESCRIPTION The JW1769A/B/C is a constant current LED regulator 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. 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. JW1769A/B/C is supplied from the output directly, and auxiliary winding is not needed.
