LED Drivers

automotiveLED driverboost converterSEPICPWM dimmingAEC-Q100HTSSOP-20

LP8861QPWPRQ1 is a qualified automotive four-channel LED backlight driver with an integrated boost/SEPIC converter and up to 100 mA per channel.

Best for

  • Automotive LCD backlights with up to four LED strings
  • Instrument clusters and infotainment displays
  • Applications needing PWM dimming and adaptive LED supply voltage

Avoid if

  • More than four independently controlled LED strings are required
  • Required converter load exceeds the integrated switch and external power-stage limits

Check before use

  • Verify LED-string voltage versus the 45 V converter output limit
  • Size the inductor for saturation current and switching frequency
  • Ground unused OUT pins
  • Connect the exposed thermal pad to the PCB thermal ground structure
