SM2082B Single Channel LED Constant Current Driver v1.6
Patented constant current control
Output current adjustable with range
Inter-chip output current deviation <±4%
Over temperature protection
Sharing PCB board with LED lamps
Excellence EMI performance
Simple circuit and low cost
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.
