Hello,
I am trying to figure out how to use TPS56221 in a 12V to 0.9V, we think 15A maximum on the whole industrial temperature range (-40°C/+85°C) environment (and a quick 1 to 5ms max on time).
I was looking into the example that is inside the datasheet but I also am intrigued by our answer on this 12V to 3.3V, 25A, at 70°C answer.
How can I be sure that my design is safe on the all temperature range ?
And if I may add a question on the example. How is the self chosen ? Because the equation gives an approximated 186nH but the 320nH is chosen wheras the same self family has 180nH and 215nH ? And the 5.8A peak to peak ripple current that is used for this self doesn't make any sense to me.
Thanks for your help.
