TRIAC DIMMABLE LED DRIVER

Description

Pin Assignments

The DIODES™ AL1692K is a high-performance, high-power factor,

high-efficiency, and high-current precision Boost, Buck-Boost, and

Flyback dimmable LED driver. The device is suited for TRIAC-

dimmable LED lamp applications and provides an accurate output

current over wide line and load regulation. It achieves higher than

90% efficiency by using a Boost topology to meet the latest high-

efficiency requirements. The wide switching frequency operates at

boundary conduction mode (BCM) to ease EMI/EMC design and

testing.

The AL1692K LED driver integrates

a 600V/2A high-voltage

MOSFET. It can cover both 120Vac and 230Vac TRIAC-dimmable

applications without the need for an external high-voltage MOSFET,

which reduces system bill-of-materials (BOM) cost. The AL1692K has

built-in thermal fold-back protection to automatically reduce output

current. Other protection features also enhance LED lighting system's

safety and reliability.

SO-7

Applications



Mains TRIAC-dimmable LED lamps

Offline LED power supply drivers

The device’s TRIAC dimming curve is compliant with the NEMA SSL6

standard and applies to a wide range of leading and trailing edge

dimmers, achieving a deep dim down to 1%.

The AL1692K is available in the SO-7 package.
