3.15 Power Supply

The power input voltage of the development board is DC12V. You can supply
power to the development board through the PCIE slot or external +12V power
supply. When use external power supply, use the power supply equipped on the
board instead of using other power supplies, to avoid damage to the development
board. The power supply on the carrier board can convert into +5V, +3.3V and 1.8V
through the 1-channel DC/DC power chip ETA8156FT2G and 2-channel DC/DC
power chip ETA1471FT2G. Because the +5V power supply supplies the core board
through connectors, the current output of the DCDC power supply is 6A, and the
current output of the other 2 power supplies is 3A.
The power supply design diagram on the board is shown in Figure 3-15-1 below:
