AL1692

DIMMABLE LED CONTROLLER/DRIVERS

Description

The AL1692 is a high performance, high power factor, high efficiency,

and high current precision buck-boost and flyback dimmable LED

controller/drivers 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 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

230Vac 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. 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.
