AL1696
HIGHLY INTEGRATION OFFLINE DIMMABLE LED DRIVER
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.

The AL1696 can be compatible 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 compliant 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.
