Power Inductors - 8 Design Tips

A practical guide for the selection of power inductors for DC/DC converters

ANP039

The power inductor selection steps described are based on the design tips given in this article and are linked to the data sheet specifications. Not only the relevant design software from the semiconductor manufacturer serves to reduce development times. With the software REDEXPERT you get a tool which identifies very quick the right inductance for a buck or a boost converter.

As a matter of course power inductors from Würth Elektronik are also listed in the leading semiconductor manufacturers‘ software solutions and hence they are immediately available for inclusion in the simulations. Correspondingly assembled design kits help optimise prototypes. Magnetically shielded power inductors should be deployed for EMC-critical applications.
