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

UCG28826EVM-093 comes populated with a USB-C PD controller along with an on-board USB-C connector to allow evaluation with a USB-C PD load which can be connected through a USB-C cable. The corresponding test setup diagram is shown in section on Section 3.2.2. USB-C PD controller can adjust the board output to obtain 5V, 9V, 15V or 20V. A USB-C PD communicating load is required for evaluation of this EVM. An example of such a load is USB-C-PD-DUO-EVM. 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 3.00A from 5V, 9V, and 15V, a standard USB-C cable can be used. To obtain 3.25A at 20V output, an "E-marker" USB-C® cable must be used.
