Part 3.22: Power Supply

The power input voltage of the AXU5EV-P 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
selected by the jumper cap. When debugging MIPI camera, select 1.2V power
supply, when using FMC interface, use 1.8V power
supply of BANK66 is +1.8V. The schematic diagram of the power supply design
on the board is shown in Figure 3-22-1:
