Power Consumption in Artix-7

Hi,
 
We are planning to use TPS65023 PMIC in my FPGA board for power supply. We are not using LDOs of TPS65023 but 3 DC-DC outputs for 1.5V, 1.2V and 1.8V. We are using separate DC-DC converters to generate 1.0V for core (4A current capability) and 3.3V and 2.5V.

We are planning to power up all the supplies together and will not be following the power on sequence. Can you please let us know in this case if the higher power up current would be able to handled by DC-DC outputs of TPS65023?
 
Thanks,

-Are you asking if the regulator can handle the power up current? I would think that would be something for you or the regulator vendor to discern. Add on to that if you are not following the recommended sequencing the power-on current could be even higher than quoted by the data sheet or XPE.

Hello, is there a Power Consumption spreadsheet available?

Thank you
