Cost-effective universal LED driver converter for general illumination needs

Digi-Key now stocks the Diodes Incorporated AL1677, a universal AC input (85 VAC to 277 VAC), high-efficiency and high-accuracy buck LED driver converter. The 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. The device's 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, says the company.
