UCC256403: Inquiry about peripheral parts used for UCC256403

Tool/software:

Thank you for your continued support. My name is Kurata.

I have the following question about the parts used in the peripheral circuit of UCC256403.

In the example circuit of the above device on the related evaluation board "UCC25630-1EVM-291",

the parts used are "C9, C11: PFR5151J630J11L4BULK (Kemet)".

Is there a reason why a film capacitor must be used for this circuit part?

Due to mounting space restrictions, I would like to use a multilayer ceramic capacitor, which has the same rating but is even smaller, but will using a ceramic capacitor cause any problems in maintaining performance?
