Parameters Subject to Change Without Notice JW18288B/JW18288C JW18288D/JW18288E PWM Dimmable Non-isolated Buck LED Regulator DESCRIPTION JW®18288B/JW18288C/JW18288D/JW18288E (JW18288X series) is a non-isolated PWM dimmable constant current LED regulator with high current accuracy which applies to single stage step-down LED drivers. JW18288X series is supplied from the line directly without auxiliary winding or external capacitor, which can lower the system BOM cost. Patented algorithms ensure good current accuracy and excellent line/load regulations. With unique sampling techniques, JW18288X series has multi-protection functions which can largely enhance the safety and reliability of the system, including LED short protection, LED open protection and over-temperature protection.
