JW19988B/JW19988C Parameters Subject to Change Without Notice Non-isolated Buck LED Driver Regulator DESCRIPTION JW®19988B/JW19988C 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. JW19988B/JW19988C is supplied from the line directly without auxiliary winding or external capacitor, which can lower the system BOM cost. With unique sampling techniques, JW19988B/JW19988C has multi-protection functions which can largely enhance the safety and reliability of the system.
