HIGH ACCURACY LINEAR CONSTANT CURRENT LED DRIVER

DESCRIPTION

The UTC UL66X is a linear constant current IC that need a

external power MOSFET. The output current is determined by

the external MOSFET, 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.

FEATURES

* Output Current is determined by the external MOSFET

* Up to ± 4% Constant Current Accuracy

* No EMC Problem

* Temperature Compensate

* Thermal Shutdown
