Power Supply Topology and Power Distribution

This section describes the implementation and circuitry that ensure adequate voltage stability for all the devices on
the board and a correct power-up sequence for the MPU. The power-up and power-down sequences indicated in the
SAMA7G5 Series data sheet must be respected for a reliable operation of the device.

3.1.1

Input Power Options

The SAMA7G54-EK board can be powered through:

• An external AC to DC +5V wall adapter connected via a 2.1 mm center-positive plug into the power jack of the

board (J1); the recommended output capacity of the power adapter is 2A

• USB port A (J7)

3.1.1.1

Wall Adapter Input

The 5V_EXT from the wall adapter is protected through a pair of Schottky/Zener diodes (D1 and D2) that limit the
input voltage to 5.1V.

The following figure shows the wall adapter input power supply topology.

USB Supply Input

The USB-powered operation comes from the USB device port connected to a PC or a 5 VDC supply. The USB
supply is enough to power the board in most applications. It is important to note that when the USB supply is used,
the USB port has limited power. If a USB host port is required for the application, it is recommended to use the
external DC supply or a more capable micro USB external power supply.

The following figure shows the USB input power supply topology.
