  • Hi Juncheng,

    Thanks for reaching out to us, my name is Mamadou Diallo and I will help address your concerns.

    Out of curiosity, how do plan on using the isolated gate driver? (What application?) Which isolated gate driver are you planning on using?

    As a starting point, I've attached couple documents for your considerations that you might find helpful.

    The first one discusses methodology for half-bridge configurations which will be applicable to your case as well

    The second below is the datasheet of one our isolated gate driver UCC21225A where section 9.2.2.2 discusses the selection of the boot diode, Cboot and Rboot.

    Thanks.
