UCC256403: Turning on cleanly with a large amount of capacitance with burst mode enabled

Part Number: UCC256403


Hello,

I'm working on a design with a lot of output capacitance that I'm struggling to get turned on cleanly with burst mode enabled. I understand that the VCR values, feedback responsiveness, and soft start cap all effect soft start time, but I'm struggling finding the right combination to get the supply to cleanly start. 

Is there anyone that can review my design worksheet and schematic in order to offer suggestions.

Thanks
