The AL1692-30B is a high performance, high power factor, high efficiency, and high current precision buck-boost and flyback dimmable LED driver for triac dimmable LED lamp applications. The AL1692-30B 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 AL1692-30B LED driver integrates a 500V/3A high voltage MOSFET. It can cover 120Vac triac dimmable applications with eliminating the external high voltage MOSFET and Varistor, which will reduce the system BOM cost. The AL1692-30B 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 AL1692-30B dimming curve is compliant with the NEMA SSL6 standard. The AL1692-30B applies to a wide range of dimmers, including leading edge and trailing edge dimmer, to achieve deep dimming down to 1%.
