Product Details

JW196738D is a constant current LED regulator which applies to single-stage step-down power factor corrected LED drivers.JW196738D integrates high voltage power source and can be supplied by line voltage directly, auxiliary winding and VCC capacitors are
not needed. Patented current sensing and digital compensation technics ensure a unit power factor and high-accuracy output current. The critical conduction mode operation reduces the switching losses and increases the efficiency. JW196738X 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
