The article about ps design is based rather on empirical observations then exact theory. Why constant 200 is used it is best to ask author.

There is no single formula. The turns number will change based on topology. Eg. the transformer design for a flyback converter will be dictated by the primary inductance. This along with other factors such as air gap will determine the number of turns.
The turns ratio and turn numbers will vary for forward, push pull, half bridge, full (...)

thanx before KB6NU, for the reply,
i'm using a ferrite core for the balun but i don't know about mu, can u give some valid reference for what kind of ferrite for mu, that suitable for VHF frequency and i need formula for the winding ratio of balun, can u give some valid reference for that too because i got a lot of reference b

The said expression is an empirical formula, that is fitted to measurements rather than calculated. There are various similar
formulas in use. As ferrite manufacturer application notes clarify, the parameters depend both on material and core shape.
I would generally suggest to use the manufacturer provided design tools for (...)

You should find out the primary inductance of the transformer. The formula relating inductance and power applies.
P = 0.5 * L * I^2 * f
P = power
L = inductance
I = current
f = switching frequency

I think Picstudent is talking about flyback transformer.
Hope someone here can explain the most reasonalbe design for flyback transformer.
The question can be more exact if we take 5V/1A output design as an example.

You do not specify what kind of transformer you want to design. There are several type of transformers and the design procedure can be very different.
