Board Component Descriptions
The VCU1287 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 3-1
. The board can also be configured to use an external bench power supply for each
voltage. See
Onboard Power Regulation
.
