Part Number: LM25118EVAL

I need to change the output voltage of the LM25118EVAL board to 28V. What components need to be changed in order to do this?

I have tried changing R8 and R9 to 22k and 1k (respectively), but this did not work. The output voltage is 0.28V. With R5 removed, with VCCX connected to GND, current limit on the input supply was hit.

What other components will need to be changed?
