SLVUCP8A September 2024 – June 2025 TPS26750
If users want to support 5V sourcing, then the power supply needs to provide at least 18W of power, due to the following board requirements:
If users want to support EPR sourcing (from 5V to 48V), then the power supply needs to provide at least 15V to the HV_SYS net (using either J3, J8. A battery can be connected to J8 for testing as well). However, the exact amount of power users need to provide depends on the expected load drawn by the sink and the highest voltage EPR contract users want to source.
The example setup in Figure 2-8 shows a 140W 3 Port PD3.1 Supported Wall Adapter, whose USB-C2 port is capable of providing 100W (20V at 5A) of power, connected to a USB-C to USB-C 100W capable cable, which is in turn connected to the Power Type C port (J3) of the TPS26750EVM. This example setup is capable of sourcing 48V of power to the DUT Type C port (J4), which is in the USB-PD Extended Power Range.
To source and sink power in the EPR range using the TPS26750EVM, users want connect a simulated battery to the HV_SYS header (J8) instead of powering the board through J3.

This figure depicts a previous version of the TPS26750 EVM (RevA2), but the information remains accurate and applicable to the current version.
