Hey Guys,
Can anyone help me here simulating flyback converter ?
I still do not understand how do we calculate the output voltage based on inductance value and turns ratio,
Attaching here .asc file.

Thanks in advance !

Have you read this.
There are many other references on the Web.

If you want a regulated 5V output, then you will need feedback from the output to control M1's duty-cycle and/or frequency.
Yes, that i understand.
My thought was, are we able to get 5V or 12V etc at output without having feedback connection.
So there will be some way of transformer turn ratio in ltspice by which we can step down the voltage.

I am not sure how do we define transformer in ltspice.

Thanks !
