SM2082D Datasheet | Linkage

Feature - Patented constant current technology a) Adjustable OUT output current: 5m A~60m A b) Output current error between chip and chip: < ± 4% - OTP - Share PCB with LED - Excellent EMC performance - Simple circuit and low cost - Package: TO252-2 - 18W LED tube manufacture with one chip Application - T5/T8 tube - LED street lamp - LED bulb lamp, LED ceiling lamp Description The SM2082D is a single channel LED constant current driver which adopts the patented constant current control technology. The output current is adjustable through the external Rext (5m A~60m A), and the chip is with excellent constant current performance that the output current is not varied with the variation of the OUT voltage. The cost is low with simple structure and fewer peripheral ponents.
