The VPK180 evaluation board uses power management ICs (PMIC) and power regulators from Infineon Integrated Circuits to supply the core and auxiliary voltages listed in the following tables. The detailed device connections for the feature described in this section are documented in the VPK180 board schematic.

The FMCP HSPC (J51) VADJ pins are wired to the programmable rail VADJ_FMC. The VADJ_FMC rail is programmed to 1.50V by default. The VADJ_FMC rail also powers the XCVC1802 FMCP interface banks 709 and 710 (see the table in I/O Voltage Rails). Documentation describing PMBus programming for the Infineon power controllers is available on the Infineon Integrated Circuits website. The PCB layout and power system design meet the recommended criteria described in the Versal Adaptive SoC PCB Design User Guide (UG863).
