Hi Kazuya,
Thank you for reaching out. Do you mean the modification on our LM5158EVAL board ( https://www.ti.com/tool/LM5118EVAL )? If yes, then more components in addition to the feedback network needs to be changed, because:
All output capcitors C9-C14…
Hi Michelle,
It will be hard to get the any switch mode power supply to work on a bread board due to parasitic components. If you would like to test on an PCB I suggest using the LM5118 evaluation module. See the link below.

Please could you update on this. We are waiting the solution and hold our design for development of this power supply.
Let us know how we could proceed further on this. We know there are 12V EVM board available for this. IS this 12V EMV tested for line…
It definitely sounds like noise coupling from SW pins is a factor in the problem. The Vin ringing would not couple through the part to the VCC pin because the VCC capacitor is much lower impedance than the internal regulator devices. There will be some…
Hi
You shcematic is almost same as EVM design, except VCCX supply and current sense filter I cannot see any issue.
Please refer http://www.ti.com/tool/lm5118eval and try R-C filter at CS pin. Also disconnect VCCX from Vout
