VP1502 chip self-monitoring of the maximum and minimum value, in the case of high power consumption

hello

   VP1502。We took four boards and ran the high-power version, and there was a board voltage alarm

The power supply of Fpga gtyp avtt102 compared with pdm is within the design value range:

High power version PDM

Design value XPE

The multimeter measured the voltage of each capacitor at the receiving end and compared it with the value read out by the FPGA: found that the value read out is relatively low.

I understand that the voltage range given by the datasheet is to the FPGA package pin, and the value read out by the FPGA is some doubt, may not detect the package pin, so there is a low thing.

Therefore, it is believed that the value read by the FPGA cannot be judged by the range of datasheet? Do you have any suggestions about this power supply?

hello,The compensated voltage is the impedance of the package multiplied by our operating maximum current?

Can you provide the following encapsulated impedance information file?
