Description

The FC2082G is a single channel LED constant current driver which

adopts the patented constant current control technology. The output current is

adjustable through the external Rext (5mA~60mA), and the chip is with

excellent constant current performance that the output current is not varied with

the variation of the OUT voltage. The cost is low with simple structure and fewer

peripheral components.
