Hello,

I am trying to build a 4 level Flying Capacitor Multi-Level Converter. I need TI solutions in the form of an IC for the Driver (including bootstrapping) for the below diagram which will have 6 switches and the following blocks. Please help me choose and gather the minimum number of ICs and solutions that can provide the below Circuit:

    Hi, Usa,

    Sorry for the delay in replying to your question - as you've probably surmised, we don't have a lot of published information on this architecture.

    You could certainly use any of our isolated drivers to drive the various switches, but as you pointed out, biasing the floating drivers is quite challenging.

    This is a popular architecture being researched - perhaps you would have better luck doing a publications search?

    Best regards,

    Don
