Xilinx KCU1250 User Manual page 12

The KCU1250 board uses power regulators and PMBus compliant digital PWM system
controllers from Maxim Integrated to supply the FPGA logic and utilities voltages listed in
Table 1-2. The board can also be configured to use an external bench power supply for each
voltage. See Using External Power

Notes:
1. The output voltages of the Max15301 can be reprogrammed using the Maxim InTune Digital Power Tool
However, extreme caution must be taken when attempting to modify any of the onboard regulators. An incorrectly
programmed regulator can damage onboard components.
