LMG3650R035 Evaluation Module
Description
The LMG3650EVM-114 features two LMG3650R035
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 LMG3650EVM-114 is configured
for a socket style external connection for easy
interface with external power stages to run the
LMG3650R035 in various applications. Refer to the
LMG3650R035 data sheet before using this EVM.
