Fast role swap power architecture: how to set R value?

hi team

I have a question in the paper of "Fast role swap power architecture white paper" which was wrote by Jacob Ontiveros from PSIL/PI/Applications.

Firstly, thanks very much for Jacob's paper.

In the equation 1, on page 6, why the R is 6Ω？

Thanks a lot!

Hi Jesse,

Jacob gives an example of ~3A current at 20V, now to draw 3A you need 6Ohm (nearest value) of resistance across the power source.

Please click "This resolves my issue" if I was able to answer your query.

Thanks,
Rahul
