OC5038 is an integrated-MOS buck constant-current LED driver for 3.1 V to 80 V LED lighting systems. It provides adjustable fixed off-time control, PWM/analog dimming, and a 90 V internal MOSFET.

Best for

  • Buck-driven high-power LED strings
  • Bicycle and motorcycle lamps
  • Flashlights and LED spotlights

Avoid if

  • Applications requiring documented automotive qualification
  • Designs requiring confirmed RoHS, REACH, MSL, or lifecycle data
  • Topologies needing an external switching MOSFET

Check before use

  • Confirm peak and average LED current using the datasheet equations
  • Verify SW voltage including transient margin
  • Provide thermal copper for the SW-connected exposed pad
  • Do not leave DIM floating
