Part 3.18: Power Supply

The power input voltage of the AXU3EGB 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:
