How can I calculate the value and characteristics of inductor in a DC to DC converter?

## Best Answer

A really great walk-through on DC-DC converter (Buck topology specifically) design calculations can be found at this Microchip Technology's web seminar slideshow. The seminar covers these important topics:

You need to know things like the input voltage, intended output voltage, acceptable input and output ripple voltage for your system/converter IC, and current requirements, as well as the switching frequency of your DC-DC converter IC.
