18. Buck Converter Inductor Selection

Rohan is designing a 24V to 5V buck converter for an embedded control board. 

The board can draw up to 2A load current. 

He has designed the converter to use a 22 µH shielded power inductor. 

Help him select a suitable SMD power inductor. 

Make sure it can handle the inductor current safely, has enough saturation margin, and keeps power loss low for efficient operation.
