Hi all!
I’m doing design of hot-swappable power supply with redundancy capability. I have used LM5050MK-1 as OR-ing controller and TPS2490DGS as hot-swap controller. Which IC should be closest to the PSU output – OR-ing or Hot-Swap?
The output stage of my PSU is here:

Two identically PSUs (A and B) will work together in redundancy mode. My concern is reverse conductivity of FET's diode. I insert PSU B in system there PSU A is already. Can hot-swap IC of PSU B correctly works then it see the output voltage from PSU A? Should I change order of ICs?
