Balun/Impedance transformer wireing?

    How does one transform the impedance of a signal from X to Y given a core from
    a switched psu (or other easy source). I can figure the wire turns ratio from:

    Zp^2 Np^2 Z=Impedance N=Turns
    ---- = ----
    Zs^2 Ns^2

    Now how to rule-of-thumb calculate the primary winding turns and area?

    What concerns me is overloading the logic chip output and/or line driver.
