12.2 Inductor Selection
Inductors should be selected based upon the following parameters:
● Rated maximum current: Usually a coil provides two current limits: The Isat specifies the
maximum current at which the inductance drops by 30 % of the nominal value. The Imax is
defined by the maximum power dissipation and is applied to the effective current.
● DC resistance: Critical to converter efficiency and should therefore be minimized.
● Inductance: Given by converter electrical characteristics; 0.47 µH for all DA9210 phases.
