DESCRIPTION
FEATURES
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. JW1758A/B/C has multi-protection functions which largely enhance the safety and reliability of the system, including VCC over-voltage protection, VCC UVLO, LED open protection, pulse-by-pulse current limit, inductor short protection and over-temperature protection.
