Diodes – AL1677 Universal High-Efficiency High-Accuracy LED Driver Converter
The AL1677 is a universal AC input (85~277 VAC), high- efficiency and high-accuracy buck LED driver converter.
The topology provides accurate constant current (CC) line and load regulation, operating at boundary conduction mode (BCM) to assist EMI/EMC qualification and testing to meet the latest regulatory laws.
AL1677 system replaces the auxiliary winding and external high-voltage MOSFET with a few external components to create a low bill of materials (BOM) cost solution.
It has comprehensive protection features to improve the system safety and reliability. The thermal fold-back function reduces the output current when the driver’s temperature is higher than the setting value.
The AL1677 is available in SO-8 package.
