評估模塊10-GEXPANSION-EVM

This is the user’s guide for the 10G-EXPANSION-EVM for use with the TPS65987EVM supporting the expansion board connector. The 10G-EXPANSION-EVM is not intended to be used alone and requires the TPS65987EVM for operation.

The 10G-EXPANSION-EVM adds to the capabilities of the TPS6598xEVM supporting the expansion board connector by allowing the user to evaluate the USB Type-C and power-delivery （PD） capabilities of the TPS6598x USB Type-C and PD devices from the power and data perspective.

The TPS6598x USB Type-C and PD controller provides cable plug and orientation detection at the USB Type-C connector. Upon cable detection， the TPS6598x device communicates on the CC wire using the USB PD protocol. When cable detection and USB PD negotiation are complete， the TPS6598x device enables the appropriate power path and configures alternate mode settings for internal and （optional） external multiplexers.

This user guide describes the TPS65987EVM and the capabilities of this EVM with the 10GEXPANSIONEVM.

電源UDO源200W USB-C PD參考設計TIDA-050012

This USB Power Delivery （PD） reference design will allow users to implement system that require more than 100 W as a power source while also highlighting the industries lowest RDSon solution. The design can output all four of the standard USB Type-C PD source

voltages of 5 V， 9 V， 15 V， and 20 V. In standard Type-C PD operation， the design will output up to 20V/4A. When Texas Instruments Power DUO mode is enabled， the design will be able to output up to 20V/10A while simultaneously lowering the RDSon by a factor of two.

This Design highlights how to implement a high powered USB Type-C PD Source device. This design can be referenced for various different end equipments， from PC Docks， Notebook PC Charger， Industrial chargers， Wall outlets， and many others. Through the use of a Texas Instruments USB Power Duo Mode， the TPS65987D PD adapter will close both of it＇s load switches in parallel to double the current carrying capability and reduce the effective RDSon by a factor of two. The design also highlights a feature of the TPS65987D called App Config by allowing users to select their Type-C PD Output voltage through push button switches. Additionally， this design goes through steps on how to implement a high powered DC/DC converter to offer the standard Type-C PD source voltages. Finally， the design also contains a P-FET bypass power path to route the input supply directly to the PD controller allowing for very high efficiency in a 20 V contract. The design also supports BC1.2 charging modes through the D+/D- USB 2.0 signals.
