Design Notes

Size the inductor for the ripple current at the actual switching frequency, typically 30% of the DC load — not for the DC rating alone.
The hot loop from input capacitor through the switch to ground sets conducted EMI. Keep that copper area as small as the layout allows.
Output ripple is set by the capacitor ESR and its DC-bias derating; a 10 µF ceramic often behaves like 4 µF at the rated output voltage.
Route the feedback divider from the output capacitor terminals, away from the switch node.
