HIGH ACCURACY LINEAR CONSTANT CURRENT LED DRIVER

DESCRIPTION

The UTC UL68D is a linear constant current IC with a built-in

power MOSFET. The output current can be adjusted from 5mA to

100mA, and constant current accuracy up to ± 3%. The application

scheme is simple and the cost is low. This device also incorporates

temperature compensation and thermal shutdown functions.
