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.
