General Description
SM2082B is a single channel LED constant current driver which integrates patented constant current setting and control technology. The output current designed by external REXT is 5m A~60m A and it is invariant to OUT output voltage change, which has better constant current performance. It is a low cost circuit with simple circuit and less external ponents.
