sbrio-9607 FPGA_VIO and 3.3V_AUX rail currents

[tobiy]

Hi,

the user manual states that the 5V output can provide 1.5A and the FPGA_VIO and 3.3V_AUX are each stated capable of delivering 0.33 A. Does that mean that they can provide 0.66 A together but each one of them can only provide 0.33 A or does it mean that they can provide 0.33 A together where each one of them can be loaded up to the full amount ?

Will the load on one of the 3.3 V rails affect the regulation of the other ?

Can the two 3.3V rails be shorted on the RMC board ?

I think you can short the two FPGA VIO as long as you set both banks at the same voltage.

At least that is what I did in my designing pcb.
