Chapter3: Board Component Descriptions
The KCU116 evaluation board uses power regulators and PMBus compliant point of load
(POL) controllers from Maxim Integrated Circuits to supply the core and auxiliary voltages
listed in Table 3-27.
The VADJ_FMC rail is programmed to 1.80V by default. This rail powers the FMC HPC0 (J5)
VADJ pins and the XCKU5P FMC interface bank 64 (see Table 3-1, page 18).
Documentation describing PMBus programming for the Maxim InTune
™
power controllers
is available at the Maxim website [Ref 34]. The PCB layout and power system design meet
the recommended criteria described in the UltraScale Architecture PCB Design User Guide
(UG583) [Ref 14].
