AL16937

NOT RECOMMENDED FOR NEW DESIGN USE AL1692S-13 AL16937 BUCK DIMMABLE LED DRIVER Description The 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. 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. Pin Assignments (Top View) VCC 1 RT 2 7D The AL16937 LED driver integrates 400V/3A MOSFET, which is suitable for 120VAC applications. The AL16937 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. COMP 3 GND 4 6 CS 5 NC The AL16937 dimming curve is compliant with the NEMA SSL6 standard. The AL16937 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.
