The AL16937-30BAS7-13 is a high performance, high power factor, high efficiency, and high current precision buck dimmable LED driver for triac dimmable LED lamp applications. The AL16937-30BAS7-13 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 AL16937-30BAS7-13 LED driver integrates 400V/3A MOSFET, which is suitable for 120Vac applications. The AL16937-30BAS7-13 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 AL16937-30BAS7-13 dimming curve is compliant with the NEMA SSL6 standard. The AL16937-30BAS7-13 applies to a wide range of dimmers, including leading edge and trailing edge dimmer, to achieve deep dimming down to 1%.
The AL16937-30BAS7-13 is available in SO-7 package.
