Nanosecond Laser Driver Reference Design for LiDAR


Design files


This light distancing and ranging (LiDAR) reference design showcases the LMG1020 and LMG1025-Q1 low side gate drivers for narrow pulse applications. These devices are capable of driving a FET to produce <1.5-ns laser optical pulses in excess of 100W.

  • Circuit capable of delivering 60A 1ns current pulses
  • Flexible platform to install and test laser diodes
  • Latest GaN FET driver technology LMG1020 and LMG1025-Q1
  • Advanced minimal-inductance layout

LMG1020EVM-006 — LMG1020 GaN Low-side Driver + GaN FET LiDAR Evaluation Module

The LMG1020EVM-006 is a small, easy-to-use power stage for LIDAR laser drive. The EVM includes an integrated resistive load, (laser not included) and takes a short-pulse input that can either be buffered (and shortened further), or passed directly to the power stage. The board can demonstrate (...)
