Power Beads - PA131xAHL Series Coupled Inductors
Gen1.5 Coupled Inductors (PA131xAHL) enables higher
efficiency compared to the Gen1.0 Coupled Inductors
(PA131xNL) due to lower switching losses in the same
package size
For use only with Volterra chipsets
Halogen Free and RoHS compliant

tion 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.
