JW1757C - Offline Step-down LED Driver

Download the JW1757C datasheet PDF. This datasheet also covers the JW1757A variant, as both devices belong to the same offline step-down led driver family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • The JW®1757A/B/C is a constant current LED driver with high current accuracy which applies to single stage step-down power factor corrected LED drivers. High voltage power MOS is integrated, which can significantly simplify the design of LED lighting system. JW1757A/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 mo.

JW1757A/B/C Offline Step-down LED Driver With PFC and High Voltage Current Source Parameters Subject to Change Without Notice DESCRIPTION FEATURES The JW®1757A/B/C is a constant current LED driver with high current accuracy which applies to single stage step-down power factor corrected LED drivers. High voltage power MOS is integrated, which can significantly simplify the design of LED lighting system. JW1757A/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.
