The AL1692 is a high performance, high power factor, high efficiency, and high current precision buck-boost and flyback dimmable LED controller/drivers for triac dimmable LED lamp applications. The AL1692 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 controller with external MOSFET can support higher output power application, up to 25W. The AL1692 LED drivers have AL1692-30BA with 400V/3A and AL1692-20C with 600V/2A MOSFET. The AL1692 platform solutions can cover both 120Vac and 230Vac applications. The AL1692 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 dimming curve is compliant with the NEMA SSL6 standard. The AL1692 applies to a wide range of dimmers, including leading edge and trailing edge dimmer, to achieve deep dimming down to 1%.

The AL1692 controller is available in SO-8 package. The Integrated MOSFET version AL1692-30BA and AL1692-20C are available in SO-7 package.
