Part 3.18: Power Supply - Alinx ZYNQ UltraScale+ AXU2CG-E User Manual

ZU3EG chip is powered on, it will detect the level of (PS_MODE0~3) to
determine the startup mode. The user can select different startup modes
through the DIP switch SW1 on the expansion board. The SW1 startup mode
configuration is shown in the following table 3-17-1.
SW1

Part 3.18: Power Supply

The power input voltage of the AXU3EG development board is DC12V. In
the carrier board, the DC12V is converted into +5V, +3.3V, and +1.8V through
one-way DC/DC power chip TPS54620 and two-way DC/DC power chip
MP1482. In addition, the Carrier board generates +1.2V through LDO to supply
power to the core board BANK65, and the power supply of BANK66 is +1.8V.
The schematic diagram of the power supply design on the board is shown in
Figure 3-18-1:
