AL1692K中文资料Triac Dimmable LED Driver数据手册Diodes规格书

描述 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.

简介

AL1692K属于集成电路（IC）的LED驱动器。由制造生产的AL1692KLED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
