DC-DC step down in FPGA

Hello there,

I have DC volt in 200V, out 50V, and I out 60A soft switch. I wonder any TI chips filter can handle this kinds of voltage. I want to use FPGA to control digital. multi phase power.

Thanks,

    Sounds like a question for TI....

    I'm not sure you've stated your requirements particularly clearly :confused:. TI have plenty of chips that will step down from 50V, but not 200V.

    Thanks a_x_h_75,

    I actually have synchronous buck converter 4 phases and each V(in) around 200V battery power.

    Vi = around 200V

    Vo = around 50V -- depend from the battery from 0V to 66V

    Io = around 60A

    L = +/- 5 percent. 7uH

    C = 22nF

    Do you think TI chip can handle this kind of loads?

    Thanks.
