Inductor Selection

Inductors should be selected based on the following parameters:

● Rated maximum current

Usually a coil provides two current limits: ISAT specifies the maximum current at which the

inductance drops by 30 % of the nominal value, and IMAX is defined by the maximum power

dissipation and is applied to the effective current.

● DC resistance

Critical for the converter efficiency and should therefore be minimized.
