I'll like to use the TPS25751 for a 100W power station

100-W source or sink?

how I'll configure the TPS25751 using the PC software, am i to use a USB to I2C cable to configure using my PC?

The PC software can only directly flashes the TPS25751EVM.The "Flash to Device" option only works on with the EVM as it interfaces with the onboard TIVA MCU when you connect the EVM to a PC running the GUI.

On a custom board, you would not have the TIVA and instead. It is expected for you to use the GUI to generate the "Full Flash Binary", then use a 3rd party EEPROM programmer to directly program the EEPROM with the full flash binary. 

As an example (not required), we use the TotalPhase Aardvark or a Dediprog tool when flashing EEPROMs not on EVMs.

And if the EEPROM is connected while being configured, does it mean the configuration files will be saved on the EEPROM and the TPS25751 can load config data from the EEPROM. 

Correct. The TPS25751 only reads from the EEPROM on initial power up. Once up and running, if the EEPROM is still connected and you reprogram it, the EEPROM will be updated with the latest configuration, while the TPS25751 continues running what was previous loaded. Once you power cycle the TPS25751, it will read the new image upon boot.

Thanks and Regards,

Chris

Very helpful, thanks a lot.
