AL1678-20B, AL1678-08B Datasheet - Diodes

AL1678-20B 500V BUCK LED DRIVER

The AL1678-20B/10B/08B is a universal AC input (85 to 277 VAC), high efficiency and high accuracy Buck LED driver. The AL167820B/10B/08B topology provides accurate constant current over line and load regulation with tight tolerance ±3%, operating at boundary conduction mode (BCM) to ease in EMI/EMC .

AL1678-20B Features

* to enhance the system safety and reliability. It has thermal fold back function, which can reduce the output current when the driver’s temperature is higher than the setting value. The AL1678-20B/10B/08B is available in SO-7 package. Pin Assignments (Top View) OUT 1 VCC 2 ROVP 3 GND 4 SO-7 7 Dra
