Part 3.20: Power Supply - Alinx ZYNQ UltraScale+ User Manual

ZU15EV 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 3-19-1.

Part 3.20: Power Supply

The power input voltage of the AXU15EG development board is DC12V. In
the carrier board, the DC12V is converted into +5V, +3.3V, +1.8V, and +1.2V,
through one-way DC/DC power chip TPS54620 and three-way DC/DC power
chip MP1482. The schematic diagram of the power supply design on the board
is shown in Figure 3-20-1:
