Electronic components for LIDAR driver

In an earlier post, we presented two LIDAR driver reference boards from OSRAM OS.

This article suggests electronic components for a pulsed LASER or LIDAR driver. The LIDAR driver comprises voltage supply with energy storage for the LASER pulse, pulse forming and the power stage for the LASER diode.

Components for the functional blocks in the image above can be found in the table below. The hyperlinks inside the table lead to our webshop rutronik24.com.
