When multiple power sources are connected at once, this circuitry is also used to 
determine the input priority level: externally connected 12V PSU 

(2)

, power over 

USB 

(3)

, and the Li-Po/Li-Ion battery 

(4)

. The transition between available power 

sources is seamless, providing uninterrupted operation of the development board.

The next PSU stage uses two MIC28511, synchronous step-down (buck) 
regulators, capable of providing up to 3A at their output. The MIC28511 IC utilizes 
the HyperSpeed Control

®

 and HyperLight Load

®

 architectures, providing an ultra-

fast transient response and high effi ciency for light loads. Each of the two buck 
regulators is used to supply power to the corresponding power supply rail (3.3V 
and 5V), throughout the entire development board and connected peripherals.

Power 12VDC, external power supply

An external 12V power supply can be connected over the DC barrel connector, 
labeled as POWER 12VDC 

(2)

. When using an external power supply, it is 

possible to obtain an optimal amount of power, since one external power 
supply unit can be easily switched for another, while its power and operating 
characteristics can be decided per application. The development board 
allows maximum current of 3A per power rail, when using an external 12V 
power supply.

The development board will be able to maintain its operating voltages within 
the specified limits, as long as the voltage of the external power supply stays 
within the range stated below, in the table. Having in mind all the additional 
peripherals that can be connected to the development board, as well as their 
power consumption, the external power supply should be considered as a 
primary power source, especially for the most power demanding applications.

Power/debug, USB-C connector

The development board can be powered over the USB-C connector, labeled 
as POWER/DEBUG 

(3)

. This connector provides power from the USB host, 

USB power bank, or USB wall adapter. When powered over the USB connector, 
the available power will depend on the source capabilities. 

Maximum power ratings, along with the allowed input voltage range in the 
case when the USB power supply is used, are given in the table Figure 2

N O T E

If the host PC is not equipped with the USB-C connector, a Type A to 
Type C USB adapter may be used.

When using PC as a power source, the maximum power can be obtained 
if the host PC supports the USB 3.2 interface, and is equipped with USB-C 
connectors. If the host PC has a USB 2.0 interface, it will be able to provide 
the least power, since only up to 500 mA (2.5W at 5V) is available from the 
host in that case.

Note that when using long USB cables or USB cables of low quality, the voltage 
may drop outside the rated operating voltage range, causing unpredictable 
behavior of the development board.

PSU connectors

As explained, the advanced design of the PSU allows several types of power 
sources to be used, offering unprecedented flexibility: when powered by a 
Li-Po/Li-Ion battery, it offers an ultimate degree of autonomy. For situations 
where the power is an issue, it can be powered by an external 12VDC power 
supply, connected over the 5.5mm barrel connector. Power is not an issue 
even if it is powered over the USB cable. It can be powered over the USB-C 
connector, using power supply delivered by the USB HOST (e.g. personal 
computer), USB wall adapter, or a battery power bank. 

There are three power connectors available, each with its unique purpose:
