Texas Instruments LMG3422R030 | Demoboard LMG3422EVM-043

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.
