Transformer for Fly-Buck convertr

Hi,

As we know for the power handling of the flyback transformer, 1/2*Lp*(Ipri-pkH^2-Ipri-pkL^2)*Fsw is used for the ccm mode (ignore the efficiency concern). I assume for the Flybuck converter is under the ccm mode too.

My question is the above mentioned equation for flyback transformer power handling is true and is also applied for the Flybuck transformer or any equation we need to use?

Regards,

Ming
