LMG3422R030 600-V 30-mΩ half-bridge daughter card

Overview

TopologyHalf-Bridge Converter symmetrical isolated
Input voltage650 V
Switching frequency2200 kHz
IC revisionB

Description

The LMG342XEVM-04X features two LMG342XR0X0 600-V GaN FETs with an integrated driver and protection in a half-bridge configuration with all the required bias circuit and logic/power level shifting. Essential power stage and gate-driving, high-frequency current loops are fully enclosed on the board to minimize power loop parasitic inductance for reducing voltage overshoots and improving performance. The LMG342XEVM-04X is configured for a socket style external connection for easy interface with external power stages to run the LMG342XR0X0 in various applications. Refer to the LMG342XR0X0 data sheet before using this EVM.

Features

  • Input voltage operates up to 600 V
  • Simple open loop design to evaluate performance of LMG342XR0XX
  • Single/Dual PWM input on board for PWM signal with variable dead time
  • Cycle-by-cycle over current protection function
  • Convenient probe points for logic and power stage measurements with oscilloscope probes that have short ground spring probes

Typical applications

  • Uninterruptable power supplies, Switch-mode power converters
  • Solar inverters and industrial motor drives
  • Merchant telecom rectifiers, Merchant network & server PSU
