AL1676
UNIVERSAL HIGH POWER FACTOR BUCK LED DRIVER Description Pin Assignments The AL1676 is a universal AC input (85~277 VAC), high power factor
(Top View) NEW PRODUCT (PF) and high efficiency Buck LED driver. The AL1676 topology
provides accurate constant current (CC) with good line and load
regulation, operating at boundary conduction mode (BCM) to ease in
EMI/EMC qualification and testing to meet the latest regulatory laws.
The AL1676 single Buck stage driver works with a single winding
inductor and High voltage MOSFET included, therefore, can use
fewer external components and create a low bill of material (BOM)
cost solution. The AL1676 has rich protection features to enhance
system safety and reliability, including under voltage lock out (UVLO),
LED open/short, over voltage, over current, over temperature
protection and thermal fold-back function which can reduce output
current when the driver’s temperature is higher than the setting value. 7 D COMP 3 6 NC 4 5 CS VCC 1 ROVP 2 GND SO-7 The AL1676 is available for SO-7 package. Features
