hi to all...

i am designing a switch mode power supply using push-pull.

i want different voltages like 5 and 3 with 12V.
A friend told me about the coupled inductor that it is a solution. i dont have any knowledge about the coupled inductor.

i just want help to do this stuff...

my input is 24 volts and im using sg3525 for pwm. the main voltage is 12v. i can generate 12 volts but converting that into 5 or 3 volts, i dont know. kindly tell me what should do. and PLZ dont post the literature. i want the exact terminology and formula to do this
 

Dear Muhammad
Hi
the coupled inductor.
I think you're referring to the multi wind transformer ? you can wind more windings and with different change ratio simply .
