Winnie,
From a first look your schematic looks good.
Maybe the MOSFET only being 3mm x 3mm might get thermally warm, consider the power loss and heat management of those components.
Please double check your component values with the quickstart calculator…
Hi SHH,
Can you fill out LM25145DESIGN-CALC?
I am unable to open that attachment, can you re-upload zip file to E2E or email me at o-murray@ti.com?

Hi Emanuele,
At first glance this looks like compensation instability.
Can you fill out a LM25145DESIGN-CALC with your values and attach it here?
If it is not the compensation values then it may be layout related.
Let me know,
