Description

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.

Features
  • 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
