Hi
i'm looking at this transformer, P3855.006 (21uH) http://productfinder.pulseeng.com/pr...heets/P719.pdf
it says primary inductance is 21uH. But turns ratio, for one set of the xfrms, is 1.33:1. So is that side also 21uH or does it scale to 16uH?
Im designing a boost converter but i want it to output two voltages, a regulated one, and an unregulated one that is ~1.33 greater. i'm trying to figure out if there will be sufficient inductance if i use this transformer.
thank you.

The rate of inductance is equal to the turns ratio squared.
Inductance can be defined in geometric terms as L = AL * N^2, being AL = u*A/l (permeability times winding cross section by winding length)
L1 = AL * N1^2 and L2 = AL * N2^2
As AL is equal for both windings,
L1/L2 = N1^2 / N2^2
L1/L2 = (N1/N2)^2
