AL1696 Datasheet | Diodes Incorporated

Description The AL1696 is a highly integrated high power factor constant current converter for mains dimmable LED driver applications. The AL1696 controls the system operating in boundary conduction mode (BCM) to ease in EMI/EMC qualification and testing to meet the latest regulatory standards. The AL1696 with build-in MOSFET solution reduces the bill of material (BOM) cost by eliminating the need of auxiliary winding and external high voltage MOSFET. Pin Assignments (Top View) NC 1 NC 2 CS 3 GND 4 7D 6 VCC 5 RT The AL1696 can be patible with a wide range of dimmers including leading edge and trailing edge dimmers. Some dimmers can achieve deep dimming down to 1%. The AL1696 dimming curve is pliant with the standard of NEMA SSL6. The AL1696 is available in SO-7 package, which provides an extra pin spacing between the high voltage MOSFET’s drain and low voltage pins to increase electricity isolation.
