AL1692K

Description

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. 

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.
