Power Beads - PA249xHL Series Coupled Inductors

Gen2.0 Coupled Inductors (PA249xHL) enables higher

efficiency due to lower switching losses and lower

conduction losses

For use only with Volterra^®multi-phase chipsets in

applications demanding a fast transient response and

high density

Halogen Free and RoHS compliant

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

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.
