The LMG3650 daughtercard features two LMG3650R070 650V 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 daughtercard is configured for a socket-style external connection for easy interface with external power stages to run the LMG3650R070 in various applications. Refer to the LMG3650R070 data sheet before using this daughtercard.
