Getting Started with the USB Power Delivery Evaluation Kit

Quick Start

EVB-PSF comes pre-programmed with a two-port source charging application with all the required jumpers configured. Steps to start exploring the PSF evaluation kit:


Mount the PM-PD modules provided in the kit on J35 and J44, as shown in Figure 2-1. Refer to the "PM-PD" section of the "Hardware User's Guide for USB Power Delivery Software Framework Evaluation Kit" article for instructions on correctly mounting these modules. These PM-PD modules can provide up to 60 W per port.

Figure 2-1 Installing the PM-PD Modules


Ensure SW2 is in the OFF position. Connect an AC to DC power supply rated for 24 V, 150 W to the DC-IN terminal (J49). Alternatively, you can also connect a bench supply to power the board.

Figure 2-2 Connecting Power Supply


Turn on SW2. You will see the VIN (D12), 3.3 V (D16), and 5 V (D13) power supply LEDs turn on. The Reset LED (D1) flashes for a second while the SAMD20 comes out of Power-on Reset (POR). The DC_DC_EN LEDs (D26 and D37) of both PD ports will turn on as well.

Figure 2-3 Powering on the Kit


Connect a PD device (e.g., phone, tablet, or laptop) to either of the PD ports using a Type-CTM to Type-CTM cable, as shown in Figure 2-4.

Figure 2-4 Connecting a PD Device


You will see the 5 V LED turn on in the LED voltmeter of the chosen port, as shown in Figure 2-4.


After the successful PD negotiation, the charging voltage and current will be increased, which will be indicated through the voltage and current meter LEDs, as shown in Figure 2-5.

A 24 VDC, 150 W supply, and adapter board are not included in the kit.
