JW19989A/JW19989B JW19989C/JW19989E Non-isolated Buck LED Driver Regulator DESCRIPTION JW19989A/JW19989B/JW19989C/JW19989E(J W19989X series) is a non-isolated constant current LED regulator with high current accuracy which applies to single stage step-down LED drivers. Operating in the boundary mode makes it high efficiency and low radiation. Patented algorithms ensure good current accuracy and excellent line/load regulations. JW19989X series is supplied from the line directly without auxiliary winding or external capacitor, which can lower the system BOM cost.
