LED driver / Constant current source

Cost-efficient, reliable and easy to use

Our linear constant current LED drivers are a simple and robust solution to drive low- and medium-power LEDs up to 250 mA – making up the vast majority of applications in the growing LED market. The AEC-Q101 qualified NCR devices are easy-to-use, reliable, cost efficient, and do not affect EMC. Reducing board space and component count, they provide stabilized output currents of 10-50 mA. The LED driver / constant current source are available in four package options: SOT23, SOT353, SOT457 and SOT223.
