TPS2660: Devices in parallel as per SLVA836

Part Number: TPS2660

I am interesting in running two TPS2660's in parallel as per SLVA836. I do not want to use the other products in this family as I don't want the additional FET for RPP. My question is if the RET lines should be connected between the two TPS2660 so as to ensure the same reference for the IMON pins?

Hi Tome,

Correct. RTNs of two devices should be connected together to ensure same reference.

Please refer attachment in https://e2e.ti.com/support/power-management/f/196/t/735218 for the test results.

Hi Rakesh,

In the attached documentation, the RTN's are not connected together?
