3.2.1 Power Supply Topology and Power Distribution

3.2.1.1 Input Power Options

Two options are available to power up the SAMA5D2-ICP board:

1. an external AC to DC +5V wall adapter connected via a 2.1 mm center-positive plug into the board’s power

jack (J1). The recommended output voltage of the power adapter is 5V at 2A.

2. the USB J-Link-OB port (J16)

The +5V from the wall adapter is protected through an NCP349 positive overvoltage controller switch. The controller

is able to disconnect the system from its output pin when incorrect input operating conditions are detected (5.83V

max).

The USB-powered operation comes from the USB J-Link-OB port connected to a PC or a 5V DC supply. The USB

supply is sufficient 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 the USB host port is required for the application, it is recommended to use the

external DC supply.

The red D3 ON LED indicates the presence of a 5V power supply from the wall adapter or from USB.

The figure below shows the input power supply topology.

USB-powered operation eliminates additional wires and batteries. It is the preferred mode of operation for any project

that requires only a 5V source at up to 500 mA.

3.2.1.2 Power Supply Requirements and Restrictions

Detailed information on the device power supplies is provided in tables “SAMA5D2 Power Supplies” and “Power

Supply Connections” in the SAMA5D2 Series data sheet.

3.2.1.3 Power-Up and Power-Down Considerations

Power-up and power-down considerations are described in section “Power Considerations” in the SAMA5D2 Series

data sheet.

3.2.1.4 Power Management

The board power management uses a Microchip PMIC, MCP16502. This is a complete, cost-effective and highly-

efficient power management solution, optimized to provide a single-chip power solution and voltage sequencing for

Microchip’s MPU series.

The MCP16502AA features:

• Four DC-DC buck regulators. Each buck channel can support loads up to 1A. Each DC-DC regulator is

optimized for its target load, namely:

– Buck 1: 3.3V for I/Os and other analog loads

– Buck 2: 1.35V for DDR3L voltage

– Buck 3: 1.25V for core voltage

– Buck 4 is unused for this application, can be accessed by users via J3 connector.

• Two 300 mA LDOs, 2.5V for VDDFUSE and 3.3V for RGB LEDs

• Support of Hibernate, Low-Power and High-Performance modes

• Interrupt flag, control PIOs and I2C interface

The default power channel sequencing is built-in, according to the requirements of the MPU. A dedicated pin (LPM)

facilitates the transition to Low-Power modes. The MCP16502 features a low no-load operational quiescent current

and draws less than 10 µA in full shutdown. Active discharge resistors are provided on each output. All buck

channels support safe start-up into pre-biased outputs.

3.2.1.4.1 Configuration

Buck 2 default voltage is selected by means of the hardwired SELV2 pin and cannot be changed on-the-fly during

operation (high-Z 1.35V DDR3L).

LDO1 default voltage is selected by means of the hardwired SELVL1 pin and cannot be changed on-the-fly during

operation (high-Z 2.5V VDDFUSE).

3.2.1.4.2 Interfacing Signals

The MCP16502 is interfaced to the host MPU by means of the following signals:

• nSTRTO (open-drain output)

• nRSTO (open-drain output)

• nINTO (open-drain output)

• PWRHLD (input)

• LPM (input) and HPM (input)

• SDA and SCL (I2C interface pins)

Note: The MCP16502 is a slave-only device without clock stretching capability. Therefore, the SCL pin is an input

only.

3.2.1.4.3 nSTRT, nSTRTO, PWRHLD Functionality

The nSTRT (push button input) serves as an external initialization input to the PMIC. nSTRT is internally pulled up to

SVIN and monitored. When the nSTRT is pulled/detected LOW (SW3 pressed), the MCP16502 initiates the turn-on

sequence.

The nSTRTO signal is asserted LOW whenever the nSTRT is detected to be LOW, and it is high-Z otherwise

(nSTRTO has an external pull-up resistor).

While nSTRT is LOW during the power-up sequence, the MCP16502 expects the assertion of the PWRHLD signal

(power-hold) from the MPU to continue the sequence.

PWRHLD may be already HIGH in a typical application using a backup supply. If PWRHLD has NOT been asserted

HIGH by the MPU before completion of the start-up sequence (i.e., when nRSTO is asserted high), the MCP16502

automatically initiates a turn-off sequence.

After the assertion of PWRHLD, nSTRT should be released before the long-press time-out timer expires.
