TPSI3052-Q1: UCC5350-Q1 as the gate driver connected to VDDH and VSSS

Tool/software:

Hello TI support team

I can't use the TPSI3052 as an isolated gate driver (I need higher gate current and faster turn-on/off time),

I wonder if I can use it as an isolated power source and use UCC5350-Q1 as the gate driver connected to VDDH and VSSS

I appreciate any help you can provide.

    Hello Yesaiahu Redler,

    Thank you for reaching out to our team on E2E.

    The TPSI3052 can provide up to 70mW of power from the VDDH pin. This power limit will limit the maximum switching frequency you can achieve. If more power is required, TI makes a family of isolated power supplies that can be found here.

    Can you provide more detail on your application? 

    Regards,
