OBSOLETE - PART DISCONTINUED PART OBSOLETE - NO ALTERNATE PART AL1678-20B/10B/08B UNIVERSAL, 500V BUCK LED DRIVER Description 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 qualification and testing to meet the latest regulatory laws. The AL1678-20B/10B/08B single buck stage system works with a single winding inductor and high voltage MOSFET included, therefore, can use fewer external ponents and create a low bill of material (BOM)...
