UCC29950 calculation

Hi team,

I see there is a graph for the MG(peak) VS QE, but doesn't tell the calculation process. Can you explain how to get this expression for  MG(peak) and QE？

Thanks a lot.

    Hello Lenna

    These curves are derived from the information and equations in the document slup263 at https://www.ti.com/seclit/ml/slup263/slup263.pdf

    Mg is calculated in equation 23 in that document and this equation was used to generate the Peak Gain Curves - see P18 of the document.
    This calculation was done by iterating Eq23 to generate curves like those in Fig 6 and picking out the maximum value for each iteration.

    Hope this answers your question - please feel free to re-post if anything is unclear.

    Regards

    Colin
