Hi Andrea,
Thanks for the update:
Below is my comments on the layout and schematic:
1. For a DCDC switching converter, it is suggested to use low ESR, Low ESL ceramic capacitor as output capacitors. So please change C1, C3~C5 to ceramic capacitors.
2. Widen the SW trace.
3. Remove the thermal relief to reduce the PCB parasitic resistance and inductance.
4. The C3~C5 GND is not connected to IC GND pad directly.
