AL1676

UNIVERSAL HIGH POWER FACTOR BUCK LED DRIVER

Description

Pin Assignments

The AL1676 is a universal AC input (85~277 V_AC), high power factor

(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.

VCC

ROVP

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.
