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 5mA~60mA 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 components.
