Hi Shay,

The schematics look good to me.

Just an observation on the inductors: The ones you are using should be fine. However, you can do with smaller values as per DS guidelines especially for the 2.5V design.

All other components like Cin, Cout, Css, FB resistors, etc. follow the recommended guidelines.

Thanks,

Amod
