产品描述

DESCRIPTION

JW®B1992S-C117/JWB1992N-C117/JWB1992M-C117/JWB1992A-C117/JWB1992B-C117(JWB19 92X-C117 series) 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.

JWB1992X-C117 series is supplied from the line directly without auxiliary winding or external capacitor, which can lower the system BOM cost. With unique sampling techniques, JWB1992X-C117 series has multi-protection functions which can largely enhance the safety and reliability of the system, including LED short protection and over-temperature protection.
