General Description

The AL1676 is a universal AC input (85~277 VAC), 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.

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.

Overview

NOT RECOMMENDED FOR NEW DESIGN NO ALTERNATIVE PART AL1676 UNIVERSAL HIGH POWER FACTOR BUCK LED.

Key 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.
