LMG3100R017: Parallel GaN design

Part Number: LMG3100R017

Tool/software:

Hi expert,

Customer wants to know if TI's GaN devices can be designed in parallel? They want evaluate TI's GaN devices in higher power system (150A-650A). 

And how can we keep parallel GaN devices switching synchronized? If we have related reference design?

Best Regards,

Ryker

    Hi Ryker,

    Yes, we can parallel our TI GaN devices and achieve higher power system. We already have schematic guidelines, test results conducted for paralleling of LMG3100 which I will share through email as we have not published them yet. Please reach out to me at my email id: r-sinha1@ti.com

    For synchronization, we are routing the PWM signals differentially so that the mismatch is minimized and externally managing the delay using RC circuits.

    Thanks & Regards,
