JW19673C Datasheet | JoulWatt Technology

DESCRIPTION The JW19673C/ JW19673D (JW19673X series) is a constant current LED regulator which applies to single stage step-down power factor corrected LED drivers. JW19673X series integrates high voltage power source, and can be supplied by line voltage directly, auxiliary winding and VCC capacitor are not needed. Patented current sensing and digital pensation technics ensure a unit power factor and high accuracy output current. The critical conduction mode operation reduces the switching losses and increases the efficiency. JW19673X series has multi-protection functions which largely enhance the safety and reliability of the system, including LED open protection, LED short protection, VIN over voltage protection and over temperature protection. pany’s Logo is Protected, “JW” and “JOULWATT” are Registered Trademarks of Joulwatt Technology Co., Ltd.
