CONSTANT CURRENT LED
DRIVER
DESCRIPTION
The UTC UL67C 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.
