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 five package options: SOT23, SOT353, SOT457, SOT223 and DFN2020D-6.

Features

  • High current accuracy
  • High power capability (up to 1250mW) for increased robustness
  • Supply voltage up to 75V
  • Parallel drivers can be used to increase the current capability
  • AEC-Q101 qualified
  • Tj = 150°
  • Leadless package option with sidewettable flanks for automatic optical inspection (AOI)
  • Space-saving and future proof
  • Easy to implement 
  • Multi-sourcing capable

Applications

  • Constant current source
  • General & Industrial Lighting
  • Consumer Electronics
  • Automotive interior and exterior lighting
    (Door handles, Dashboard, Number plate light, Indicators, Rear lights)
