Re: DC-DC step down in FPGA

Altera_Forum · ‎11-19-2013

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.
