RTK-251-DRPEVB Instruction Manual

This is the single port reference design that converts USB Type-C® input power to DC output or DC input to USB Type-C® output sourcing power.

The USB Type-C® port is dual role power (DRP) and supports both sink and source modes.

By using a dedicated FW, this board can also function as a USB PD Exerciser (sends or responds to USB PD commands like a real device) that can be used to investigate or analyze USB PD communications.

The following tool is provided for firmware customization:

  • Firmware generation support tool (PDC image generator, PDC-IMGGEN): GUI tool that can change parameters of USB PD protocols
