Design files

Overview

This reference design details a solution to drive and control 30 LEDs individually for automotive interior dome light applications. The high pixel count can be used to create different light zones or welcome light animations. The design also implements LED multiplexing functionality to control up to 150 LEDs. It uses a step-down voltage converter, a linear voltage regulator, three linear LED drivers with serial peripheral interface (SPI), and a microcontroller LaunchPad™ development kit.

Features
  • High pixel count
  • LED multiplexing (150 LEDs)
  • CISPR25 compliant
