The AM571x IDK EVM uses an external 5V power supply. The 5V power input is converted into different voltage levels to provide power inputs to the AM571x processor and other circuitry.
Early versions of the AM571x IDK EVM shipped with the GlobTek, Inc. external power supply with the part number TR9CA6500LCP-N, model number GT-43008-3306-1.0-T3. This external power supply is rated for an output voltage of +5VDC with an output current up to 6.5A. This external power supply contains applicable regional product regulatory/safety certification requirements for most worldwide locations. If you cannot use this supply, one with equivalent ratings that is approved for your location must be obtained.
Note that recently sold IDK EVMs do not ship with a power supply in the box due to international concerns. Also note that the power supply listed above is being discontinued. The manufacturer has provided a drop-in replacement. This is the TR9CA8000LCPIM(R6B), which is readily available from distributors such as Digikey.
The AM571x IDK EVM contains a right angle mounted power connector that accepts the +5VDC supply input on the center pin with the outer shell as the common return. The power connector accepts a mating plug with a 2.5mm ID and a 5.5mm OD.
Removing the power plug and inserting it again while the power supply is energized can damage the AM571x IDK EVM or other devices attached to the board such as emulators that provide an alternate path to ground. Removal of AC power from the external power supply is a safer method, if required.
It is recommended that the external power supply have the common return bonded to earth ground. If this is not possible, a separate connection from the board ground to earth ground may need to be provided. Terminal block J53 is added for this purpose.
