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.
