Hello

I don't see anything wrong in the schematic.

Please use the calculator tool spreadsheet for this device to unsure you have proper component selection.

You may want to leave a place holder on the PCB for a feedforward capacitor if needed (see calculator tool)

Ensure that the inductor is rated for the current limit of the device; about 2.5A

C158 and C156 could be closer to the device.

I would swap the locations of C159 and C154. Connect FB near to C154

I assume you have a good ground plane under the device to provide good heatsinking.

Please be sure to follow all recommendations in the data sheet.

Calculator is attached here.

Thanks
