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.
