WEBENCH® Tools/TPS548D21: TPS548D21

Part Number: TPS548D21

Tool/software: WEBENCH® Design Tools

Hello,

 I am using TPS548D21 in one of my project and I found in datasheet like Feedback resistors on RSP & RSN should be much lesser than 100K.

But in webench tool when i simulated the schematics I could find that it has used 124K on RSP pin.

Can you please explain me what would happen if I go for lower resistance value on Rfbb?

Hereby I have attached the Datasheet wording and Webench schematic too.

Thank you.
