Hi Fengyu,

I am not sure if I got all the data but if I got it right the switching frequency is 500kHz and the inductor should be 1uH.

In this case the saturation current of the inductor needs to be > 8A. (Inductor peak current is 6A).

I could not do the math for all components.

Best regards,

Stefan
