Introduction
This Application Note provides design information to help
select an off-the-shelf inductor for any continuous-mode
buck converter application.
The first part shows how the designer should estimate his
requirements, specifically the required inductance.
The next part takes an off-the-shelf inductor and shows how
to interpret the specs provided by the vendor in greater
detail. A step-by-step procedure is provided.
Finally, all the previous steps are consolidated in a single
design table, which answers the question: “How will the
selected inductor actually perform in a specific application?”
The important point to note here is that though every induc-
tor is designed assuming certain specific ‘design conditions’,
that does not imply that these conditions cannot be varied. In
fact every inductor can be satisfactorily used for many appli-
cations. But to be able to do this, the designer must know
how to be able to accurately predict, or extrapolate, the
performance of the inductor to a new set of conditions, which
are his specific ‘application conditions’.
