TPS62913: Inductor Selection for the First L-C Filter

Part Number: TPS62913


I am trying to design DCDC from 9V to 5V@1.5A max.

When I choose the inductor value I see in the datasheet the next spec: "If Dmax is above 45%, only use a 4.7-µH inductor."

When I use TI WEBENCH, it is recommended to use 2.2uH even when the Dmax is above 45%.

What value of the inductor should I take ? 4.7uH ?
