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.

Page 5: Description
Description www.ti.com Description The LMG3410EVM-031 operates as a daughter card as part of a larger custom designed system or with the LMG34XX-BB-EVM breakout motherboard. LMG3410EVM-031 The LMG3410EVM-031 configures two LMG3410R150 GaN FETs in a half bridge. All the bias and level shifting components are included, allowing low side referenced signals to control both FETs. - Page 6 Figure 5. To disconnect from the boostrap mode, D1 and R2 needs to be removed. Do NOT power up the LMG3410EVM-031 when R1, R2 and D1 are all populated with the isolated power supply board connected. 2.1.5 Heatsink The heatsink is installed to help with heat dissipation of the LMG3410R150.

- Page 8 12V input is used to power the two LMG3410R150 devices. A linear drop off regulator steps the voltage down to a tightly regulated 5V for logic power of the LMG3410R150. When the LMG3410EVM-031 is configured in isolated power supply mode the 5V is also used for auxiliary power for the top LMG3410R150 Q1.
