Power supply with minimum current capability of ...A for system startup is recommended.

For the lowest power consumption and highest efficiency of the on-board DC-DC regulators it is recommended to power the module from one single 3.3V supply. All input power supplies have a nominal value of 3.3V. Although the input power supplies can be powered up in any order, it is recommended to power them up simultaneously.

The TEB0911 UltraRack board is equipped with the Xilinx Zynq UltraScale+ MPSoC delivers a heterogeneous multi-processing system with integrated programmable logic and independently operable elements and is designed to meet embedded system power management requirement by advanced power management features. This features allow to offset the power and heat constraints against overall performance and operational efficiency.

This features allowing highly flexible power management are achieved by establishing Power Domains for power isolation. The Zynq UltraScale+ MPSoC has multiple power domains, whereby each power domain requires its own particular on-board DC-DC converters.

The Processing System contains three Power Domains:

• Battery Power Domain (BBRAM and RTC)
• Full-Power Domain (Application Processing Unit, DDR Controller, Graphics Processing Unit and High-Speed Connectivity)
• Low-Power Domain (Real-Time Processing Unit, Security and Configuration Unit, Platform Management Unit, System Monitor and General Connectivity)
• Programmable Logic (PL)

There are following dependencies how the initial 24V voltage from the main power jack J34 is distributed to the on-board DC-DC converters, which power up further DC-DC converters and the particular on-board voltages:

The TEB0911 UltraRack board meets the recommended criteria to power up the Xilinx Zynq UltraScale+ MPSoC properly by keeping a specific sequence of enabling the on-board DC-DC converters dedicated to the particular Power Domains and powering up the on-board voltages.

On the TEB0911 UltraRack board following Power Domains will be powered up in a certain sequence with by enable and power-good signals of the DC-DC converters, which are controlled by the System Controller CPLD U27:

1. Low-Power Domain (LPD)
2. Programmable Logic (PL) and Full-Power Domain (FPD)
3. GTH, PS GTR transceiver and DDR memory

Hence, those three power instances will be powered up consecutively and the Power-Good-Signals of the previous instance is asserted.
