AL1677 Datasheet High Efficiency And ACcuracy Led Driver Converter

Manufacturer: Diodes Incorporated

Overview: NEW PRODUCT AL1677 UNIVERSAL, HIGH EFFICIENCY AND ACCURACY LED DRIVER.

General 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 ponents to create a low bill of material (BOM) cost solution.

Key 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.
