40-V to 80-V adjustable output voltage boost reference design for LIDAR applications


Design files


This reference design utilizes a non-synchronous boost controller to provide an adjustable output of between 40 V and 80 V capable of delivering a maximum of 100 mA of current to the load. This is an automotive design intended to power various applications such as LiDAR systems, which require an adjustable voltage supply.

  • Easy to configure adjustable output
  • High power density
  • Wide output range with stable loop response
  • Low BOM cost
