Parameters Subject to Change Without Notice DESCRIPTION The JW®1969A/JW1969B/JW1969C/JW1969D/ JW1969E/JW1969BC/JW1969DC/JW1969EC (JW1969X series) is a constant current LED regulator which apply to single stage step-down power factor corrected LED drivers. JW1969X 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 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.
