Please kindly help to check our schematic.
Our input range is 42V to 58.8V, and output power is 25V/3.5A.
Looking forward your feedback.
Thanks a lot.

Are you working with Jamie? I am reviewing a similar schematic with her.
BTW, LM5149 VCC and gate drive is only 5V, it will not be able to drive that SPR60N10SV-C MOSFET effectively.
You need to use logic-level MOSFETs, these usually have specs for VGS = 4.5V.
See SPR103N10S-C for example
