Diodes' AL1692 is a high performance, high power factor, high efficiency, and high current precision buck-boost and flyback dimmable LED controller / driver 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 25 W. The AL1692 LED drivers have the AL1692-30BAS7-13 with 400 V / 3 A and AL1692-20CS7-13 with 600 V / 2 A MOSFET. The AL1692 platform solutions can cover both 120 V_AC and 230 V_AC 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 and applies to a wide range of dimmers, including leading edge and trailing edge dimmer to achieve deep dimming down to 1%.

The AL1692S-13 controller is available in SO-8 package. The Integrated MOSFET version AL1692-30BAS7-13 and AL1692-20CS7-13 are available in SO-7 package.
