TPS65981: Test of TPS65981EVM alone (no DP-EXPANSION-EVM) connected to a USB-C PD power supply

Part Number: TPS65981
Other Parts Discussed in Thread: , DP-EXPANSION-EVM

Hi,

Would you kindly comment what is the minimum evaluation board setup required to test an external USB-C PD power supply?

We intend to have our design fed through TPS65981 connected to an external power supply (an off-the shelf item not monitorable), and USB data communication is not needed.

To speed the design, we'd like to test the topology using eval boards, but we are not sure if only 1 unit of TPS65981EVM is enough for monitoring the power delivery, and also not sure if DP-EXPANSION-EVM is needed.

Hi Newton,

the TPS65981EVM by itself is more than sufficient to test all of the power requirements of your application. The DP Expansion EVM is only needed when you want to pass USB data or video through the EVM. For testing power, the TPS65981EVM is all you will need.

If this answers your question, PLEASE select This resolved my issue

Thank you,

Eric

Thank you, Eric.

May we get the Altium files of TPS65981EVM? We'd like to speed up our design, anticipating thermal and RF simulations.

Best wishes,
