The magnetic flux calculation in QR flyback.

Hi TI team

I'm Andy

I'm confused about the magnetic flux calculation in QR flyback.

How to calculate the magnetic flux at on-time and rest/off time?

I think these will be balanced at a period/cycle.

thanks

Hi
I don't see the calculation of magnetic flux in the datasheet.
I know how to calculate the current and voltage.
I design a transformer, but I don't how much the magnetic flux it created at on-time and reset at off-time.
