Diodes' AL16937 is a high performance, high power factor, high efficiency, and high current precision buck dimmable LED driver for triac dimmable LED lamp applications. Its 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.
The AL16937 LED driver integrates a 400 V/3 A MOSFET, which is suitable for 120 VAC applications. It has the built-in thermal fold-back protection trigger point to automatically reduce output current. Other protection features enhance LED lighting system's safety and reliability.
The AL16937 dimming curve is compliant with the NEMA SSL6 standard. It applies to a wide range of dimmers, including leading edge and trailing edge dimmer, to achieve deep dimming down to 1%.
The AL16937 is available in SO-7 package.
