Yes..the 1:1 core you showed me in post #18 above cannot do 5vout from 5vin in pushpull connection...neither with currnt doubler connection, nor split coil output.
The attached ltspice , which is pranged to be on abs max duty cycle, shows it cannot do 5vout from 5vin
Do you still want to do the pushpull now?
The chances of finding one with the right turns ratio, i woudl have thought, is very slim...
flyback instead?

anyway, i think you get the general picture, you do di = V.dt/L to get the magnetising current rise...then check its not greater than 300mT.
