LMG3410R050: GAN power Switch in parallel Configuration

Part Number: LMG3410R050

Sir,

I am designing 2.5 KW High Frequency XRAY Machine. My XRAY frequency will be 50 kHz. I need to convert  DC voltage into 50kHz AC Square Wave. Then i will feed this ac into a transformer.

Can i use LMG3410R050 ? But My current requirement is higher. Can i connect LMG3410R050 in parallel like IGBT to double the current carrying capability ???

    Hello Ehsan,

    Yes, you can use the LMG3410R050 in parallel to increase the current/power capabilities.

    A quote from the R070 datasheet but can still apply here is:

    LMG341xR050s can be paralleled directly in soft-switching applications. As for hard-switching applications, small decoupling inductors should be utilized to parallel the two half-bridge LMG341xR050s. This type of setup prevents current and thermal unbalances among the parallel devices due to any propagation delay and gatesource threshold voltage mismatches, and other factors.

    You should follow these guidelines while designing your circuit.

    Hope this helps!

    Regards,
