Good day to the TI support staff,
I'm a board designer and my project is planning to use Xilinx's new Versal series of FPGAs.
I looked at your current line up of rad-hard regulators(which we already use on other boards of ours), but I'm wondering if you had potential commercial regulators that you are planning on generating a rad-hard variant?
I'm asking because the Versal has some very high current power rails with some tight ripple constraints.
For example, the 0.88V(analog) and 1.5V(analog) rails on the Versal are asking for 10mV peak to peak ripple.
Considering that most available space grade regulators can only provide about 1.5-3% or more output ripple, it's looking quite dire for us.
Another example, the 0.7V(digital) rail will easily draw 30-60A. So, our best option, for now, was to use your TPS7H4001-SEP regulators in parallel. You can imagine the power dissipation is serious on these bad boys.
If you have any suggestions or solutions for power management with the Versal, then I'll be more than happy to hear it.
Cheers,
Gabriel Karras
