Description
AI
The AL1698K is a high efficiency, high performance, high power factor, and high current precision boost, buck-boost, and flyback dimmable LED driver for triac dimmable LED lamp applications. The device provides an accurate output current over wide line and load regulation. It can achieve higher than 90% efficiency by using a boost topology to meet the latest lighting regulatory high efficiency requirements. The wide switching frequency operates at Boundary Conduction Mode (BCM) to ease EMI/EMC design and testing.
