TPS62480: TPS62480 SW node layer and Feedforward Capacior question?

Dear support member,

My customer used TPS62480.

I have two question.

Q1. About Feedforward Capacitor

Feedforward Capacitor is recommend value 36pF.
Is there a problem when using 100pF?

How is the number of Fzero-CF value?

Q2. About SW node

I have attached file.
There is SW node copper pour area on internal or bottom layer of TPS54335A.

Can TPS62480 use SW node in the same way as TPS54335A?

Could you check attached file?

Best regard.
Bob Lee.
