Feature Descriptions
The ZC702 board uses power regulators and a PMBus compliant system controller from
Texas Instruments to supply core and auxiliary voltages as listed in Table 1-30. The Texas
Instruments Fusion Digital Power graphical user interface is used to monitor the voltage
and current levels of the board power modules.
