LP8867QPWPRQ1 is a four-channel automotive LED backlight driver with integrated boost or SEPIC power conversion and up to 120 mA regulated current per channel.

Best for

  • Four-string automotive LED backlights
  • Applications requiring adaptive LED supply voltage
  • Boost or SEPIC LED power stages with PWM dimming

Avoid if

  • More than four independently regulated LED strings are required
  • LED current above 120 mA per uncombined channel is required
  • The required converter voltage exceeds 45 V

Check before use

  • Confirm the selected boost or SEPIC topology meets the VIN and LED-string voltage range.
  • Confirm SW voltage remains within protection limits, especially in SEPIC operation.
  • Follow the recommended high-current layout and grounding guidance.
