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