Hey all,

i am trying to find the MOSFETs minimum on resistance for the Inifineon BSC0902NSI. This is for the calculation on page 17 of the ADP1850 buck converter.

I can't seem to make sense out of the part where it says "SETTING THE CURRENT SENSE GAIN" on the same page. I have the values calculated for Vcsmin, Vcsmax and Vcompmax with 0.516, 0.93 and 0.93 respectively but how is the Rcsg determined with these ? Well it clearly says 'select' but on what basis ? The Rdson max is 0.0038mOhm based Diagram 9 in the mosfet's datsheet.
