2.2 Power Requirements

The AM261x LaunchPad is powered from a 5V, 3A USB type-C input. The following sections describe the power distribution network topology that supply the AM261x LaunchPad, supporting components and the reference voltages.

Power supply solutions that are compatible with the AM261x LaunchPad:

  • When using the USB type-C input:
    • 5V, 3A power adapter with USB-C receptacle
    • 5V, 3A power adapter with captive USB-C cable
    • PC USB type-C port that has Power Delivery classification
      • Thunderbolt
      • Battery behind USB logo

Power supply solutions that are NOT compatible with the AM261x LaunchPad:

  • When using USB type-C input:
    • Any USB adapter cables such as:
      • Type-A to type-C
      • micro-B to type-C
      • DC barrel jack to type-C
    • 5V, 1.5A power adapter with USB-C captive cable or receptacle
    • PC USB type-C port not capable of 3A
