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 components and create a low bill of material (BOM) cost ...
