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.

SM2082B Single Channel LED Constant Current Driver v1.6
(1) To ensure the normal operation, output voltage should be VOUT > VOUT_MIN;
(2) Lower output voltage brings higher system efficiency.
Basing on the two points above, SM2082 output voltage range is VOUT_MIN ~ VOUT_MAX and LED series
number formula is:
