Hi Expert,
I see in datasheet below. Could you please tell how equation 13 and 14 come from? Thanks.

Hi Elec,
Equation 13-----assume it takes 6 cycles for the control loop to regulate inductor current from IOL to IOH, Cout will discharge at current (IOH-IOL)/2 for 6 cycles, then Cout can be calculated accordingly.
Equation 14------Inductor storage energy is I^2*L/2, Capacitor storage energy is V^2*C/2, this equation delivered by inductor reduced energy is same as it increased in output cap,
