AL1692 DIMMABLE LED CONTROLLER/DRIVERS Description Pin Assignments The AL1692 is a high performance, high power factor, high efficiency, (Top View) and high current precision buck-boost and flyback dimmable LED controller/drivers for triac dimmable LED lamp applications. The 7 SW VCC 1 D 1 8 VCC AL1692 topology provides an accurate output current over wide line NC 7 RT 2 RT 2 and load regulation. The wide switching frequency operates at COMP 3 6 CS boundary conduction mode (BCM) to ease EMI/EMC design and COMP 3 6 CS testing, to meet the latest regulatory standards. 5 4 5 GND 4 FB GND FB The AL1692 controller with external MOSFET can support higher SO-8 SO-7 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 Applications 230Vac applications. The AL1692 has the built-in thermal fold-back Mains Dimmable LED Lamps protection trigger point to automatically reduce output current. Other Offline LED Power Supply Driver 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.
