Tool/software:
Hello,
Going through SN6507 transformer calculations I noticed the datasheet refers to "Turns Ratio" as Ns for Np=1 (see Table 9-3).
That's convenient since it's how most push-pull transformers are spec'd, but is inconsistent with typical transformer nomenclature where 'Turns Ratio" = Np/Ns.
This means the calculations in 9.2.2.5.2 actually give the reverse result... lower Vin needs more turns on the secondary, which is a **lower** conventional Turns Ratio Np/Ns.
I spent a bit of time grinding on this problem, perhaps the datasheet can be amended to clarify this. Thanks!
