Description

The AL16937 is a high performance, high power factor, high efficiency, and high current precision buck dimmable LED driver for triac dimmable LED lamp applications. The AL16937 topology provides an accurate output current over wide line and load regulation. The wide switching frequency operates at boundary conduction mode (BCM) to ease EMI/EMC design and testing, to meet the latest regulatory standards.
