UCC28810: Using UCC28810 as PFC Power Supply Controller not as LED lighting PFC Controller

Part Number: UCC28810

I was given a project that is using UCC28810 LED driver IC.  In the design they are not driving LED's they are just producing 24 Volts DC at 2 amps straight power supply.  What  are the issues with doing thi type of thing?  We we are seeing is excessive noise on the 24 volt outputs.  Would it be possible to give me some guidance as what would be the proper way to do this design.  Again we have the supply running but we are seeing excessive current spikes on Fet at turn on and turn off.

Regards

Scott
