Kit operation
6. Remove the multimeter and connect an external load to the terminal block (J9 for Port 0 and J15 for Port 1)
to sink the power output.
The maximum current that can be consumed by an external load is limited to 5 A by the USB
Attention:
PD specification. If the load exceeds 5 A, the USB-C power adapter may trigger overcurrent
protection (OCP) and cut off the power supply to the kit. This behavior is dependent on the
implementation of the USB-C power adapter.

USB PD source operation

The EVK switches to Source mode if powered via an external power supply at the DC input terminal (J11) or the
DC input barrel jack (J12). The EVK supports up to a maximum contract of 20 V and 5 A (100 W) in the Source
mode. When a Type-C device is connected to any of the USB PD Type-C ports (J10 for Port and J14 for Port 1) of
the EVK, the EVK offers the PDOs of 5 V, 9 V, 12 V, 15 V, and 20 V on the connected port. The connected Type-C
device should be compatible with one of these PDOs to test the source operation successfully.

Follow these steps to operate the EVK in the USB PD Source mode:
1. Set the kit in Operational mode by placing a jumper shunt on the power selection jumper (J5) at position 1-2
to select the 3.3 V LDO (powered by the DC input) as the power source for the EVK.
