JW1965A/JW1965B/JW1965C Boost LED Driver With Power Factor Correction Parameters Subject to Change Without Notice DESCRIPTION The JW®1965A/JW1965B/JW1965C (JW1965X series) is a constant current LED driver which applies to single stage Boost power factor corrected LED drivers. JW1965X series integrates high voltage power source, and can be supplied by output voltage directly, auxiliary winding and VCC capacitor 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.
