SMT POWER INDUCTORS

Power Beads - PA131xNL Series Coupled Inductors

NOTES:

tance during transient and steady-state conditions. As a result, any attempt to

lower the inductance to improve transient response has the negative result of

increasing ripple and peak currents throughout the system during steady-state

operation. However, in a coupled inductor multi-phase topology, the interaction

of magnetic fields from each phase enables an overall reduction in ripple

current during steady-state operation and a lower equivalent inductance

during transient operation. The equivalent transient inductance per phase, as

listed, represents the actual value of inductance that would be required in an

non-coupled topology to realize the same transient performance. This value is

achieved by core and winding geometry and is not directly measured by Pulse.

For more information on the operation of the coupled inductor topology, please

Pulse production measurement. Although the equivalent inductance per phase

during steady-state is significantly higher then the equivalent transient induc-

tance as listed, it should not be confused with the magnetizing inductance.
