The LMG3410EVM-031 features two LMG3410R150 600V GaN power transistors with integrated drivers
that are configured in a half bridge 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
parasitic inductances, reducing voltage overshoots and improving performance. The LMG3410EVM-031 is
configured to have a socket style external connection for easy interface with external power stages to run
the LMG3410R150 in various applications.
