NEW PRODUCT AL1677 UNIVERSAL, HIGH EFFICIENCY AND ACCURACY LED DRIVER CONVERTER Description The AL1677 is a universal AC-input (85~277 VAC), high-efficiency and high-accuracy Buck LED-driver converter. The AL1677 topology provides accurate constant current (CC) 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 AL1677 system removes the auxiliary winding and external highvoltage MOSFET with few external components to create a low bill of material (BOM) cost solution. The AL1677 has rich protection features to enhance system safety and reliability. With thermal foldback function, the AL1677 can reduce output current when the driver’s temperature is higher than the setting value.
