If you have Vin measured at Vout, it is very likely the top FET has failed. Did your design ever work?

As Ambreesh mentioned, the schematic did not show up. Please can you try to repost?

Thanks.

The issue is the direction of the source and drain at FET..

After we changed the source and drain of FET, it' working

Thanks,

Nick
