CONSTANT CURRENT LED

DRIVER



DESCRIPTION

The UTC UL66C is a linear constant current IC with a

built-in power MOSFET. The output current can be adjusted

from 5mA to 60mA, and constant current accuracy up to ± 4%.

The application scheme is simple and the cost is low. This

device also incorporates temperature compensation and

thermal shutdown functions.
