Non-isolated Buck LED Driver Regulator
DESCRIPTION
JW®B1997N/M/A/B is a non-isolated constant current LED regulator with high current accuracy which applies to 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.
JWB1997N/M/A/B is supplied from the line directly without auxiliary winding or external capacitor, which can lower the system BOM cost.
With unique sampling techniques,
JWB1997N/M/A/B has multi-protection functions which can largely enhance the safety and reliability of the...
