flux in torroid

I need to wind a toroid of 330uH for the output coil of a switcher (LM2576).

By formula calculator and measurement I have reached a coil design.

But I have to consider saturation current also before finalizing .How to do that?
Saturation flux of my ferrite material as per datasheet is 480.

My inductor needs to handle 2Amps.

Please help
 

calculate saturation current of inductor

u take v=L.di/dt & v=n.d(phi)/dt and B =(phi)/A and get from that as well as you know saturation flux density of the ferrite toroid core.

FROM ABOVE INFO u get it
