TPS62090 Feedback resistors and SS limits

Hi,

I have a WBench design using the TPS62090 to create a 3V0 2A supply from 3.3 to 5V input.

Two questions:

1. Feedback resistors:

Do the values have any impact on the compenation loop?

432k and 158k are proposed by WBench.  Can these be changed to say 43k2 and 15k8?


2. SS capacitor:

WBench is suggesting 3n9  ( with bounds of 3.56 and 4.32). 

Looking at the data sheet I can't see  any reason this cannot be increased to say 10n?

Is this okay, and why is WBench restricting the range?


Thank you,

Marc
