AL1697 Datasheet Offline Dimmable LED Driver

Manufacturer: Diodes Incorporated

General Description

The AL1697 is a high performance, high power factor, high efficiency and high precision buck-boost LED driver for mains dimmable LED lamp applications.

The AL1697 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.

Overview

AL1697 HIGH PF, OFFLINE DIMMABLE LED DRIVER WITH INTERNAL HIGH-VOLTAGE.

Key Features

  • to enhance system safety and reliability. The AL1697 starts reducing output current when the driver’s temperature is higher than the built-in thermal foldback protection trigger point.
