2.2 Using the EVM on a Load with USB-C PD Communication

LMG3622EVM-082 comes populated with a USB-C PD controller and requires external connection through an on-board USB-C connector to a USB-C PD load to adjust the board output to obtain 5-V, 9-V, 15-V or 20-V. A USB-C PD communicating load is required to make the board evaluation. An example of such a load is PM125, USB Power Delivery Tester and PassMark Software. Without such a communication load, the board output USB-C connector (J2) does not provide a variable output voltage. To obtain the full load current 3.00-A from 5-V, 9-V and 15-V, a standard USB-C cable can be used, but to obtain 3.25-A at 20-V output, an "E-marker" USB-C cable has to be used. In case the EVM is desired to test on a load without USB-C PD communication, the next section describes how to modify the board to make this test.
