When cascading a ferrite bead and inductor in the form C-L-C-L-C, which is best to put first, particularly for a buck converter?
For the input filter, it's important to have the capacitor close to the supply terminal, with a small loop area to GND. This cap supplies the high-side transient.
This would imply C-L-C-L-C input ...

Comparative Analysis: IC Buck Converters vs. General Buck Converter Schematics
When the switch transistor in the converter chip turns off, the voltage at the left end of the inductor wants to go negative. The diode shorts this to GND, which sends the energy in the inductor to ...
