smt POWer inductors
Power Beads - PA131xNL Series Coupled Inductors
Gen 1.0 Coupled Inductors (2,3,4 and 5 phases)
For use only with Volterra chipsets
Coupled Inductors enable:
•Phase ripple current reduction due to AC magnetic
field cancellation within the inductor core
•Improved efficiency due to lower peak currents
•Reduction in required output capacitance

Notes
1.In a non-coupled multi-phase topology, the power supply
sees the same inductance 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 contact Volterrra.
2.The rated current per phase is based on Volterra’s testing of the
Pulse coupled inductors.
3.The open-circuit inductance per phase is the measured inductance
(at specified current) across each phase when all other phases are
open-circuit. The open circuit inductance is equal to the magnetizing inductance per phase (Lm) plus the equivalent transient
inductance (Lk).
4.The nominal value of DCR/phase is for reference only. For production testing, the maximum limit is used.
