TPS65981 USB Type-C™ and USB PD controller, power switch, and high speed multiplexer EVM


Order now


The TPS65981EVM is a complete reference design for USB Type-C and Power Delivery Applications featuring a variable DC/DC architecture to optimize board layout and minimize BOM cost.  In addition, when paired with the DP-EXPANSION-EVM the user can emulate a full-featured USB Type-C PD host or device.

  • USB Type-C testing and verification
  • USB Power Delivery testing and verification
  • Application Emulation (EPOS, TV, Monitor, Charger)
  • Powered from single supply and bus-powered capable
  • DisplayPort Alternate Mode and USB Data verification (when used with DP-EXPANSION-EVM)
