TPS54260-Q1: Where do I find KIND values of inductor ?

Part Number: TPS54260-Q1

In the design document calculations use the value of Kind. Where do I find this value.

This is mentioned in reference http://www.ti.com/lit/an/slva412/slva412.pdf equation 4.

Thanks,

    KIND is a coefficient that represents the amount of inductor ripple current relative to the maximum output current.
    In this document ,the KIND is 30%.You can see the words in the section 2.2 in this PDF.(also show you in the below)

    2.2 Output Inductor Selection
    The output inductor is typically selected so that the peak-to-peak ripple current is 30% of the output
    current. Verify that the RMS and saturation current ratings for the inductor exceed application
    specifications.
