AL1676 Overview
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...
