JWB1997M
DESCRIPTION
JWB®1997M/A 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.
JWB1997M/A is supplied from the line directly without auxiliary winding or external capacitor, which can lower the system BOM cost.
With unique sampling techniques, JWB1997M/A has multi-protection functions which can largely enhance the safety and reliability of the system, including LED short protection and over-temperature protection.
