UCC21225A: decrease the switching speed UCC21225A

Hi ,

just want to check if there is how to decrease the switching speed in UCC21225A.

Customer use UCC27201 before and is now testing on UCC21225A in Buck topology. Since the driver capability is stronger than UCC27201, they find the spike of SW is larger.  So they want to know if adding resistor on boot is still OK for UCC21225A to decrease the switching speed.

Thanks.
