Power Inductors: 8 Design Tips

A practical guide for the selection of power inductors for DC/DC converters. Switching regulators are becoming increasingly important thanks to their high efficiencies. The trend is towards regulators with output voltages lower than 1 V, load currents up to 60 A and switching frequencies up to 8 MHz. At the same time, users demand the smallest possible types. But what has to be taken into account when using power inductors?
