SMT POWER INDUCTORS
Power Beads - PA314xHL Series Coupled Inductor
Gen 3.0 Coupled Inductors (2, 3, 4 and 5 phases)
For exclusive use with Maxim VPR devices
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
Electrical Specifications @ 25°C - Operating Temperature -40°C to +130°C

Notes:
to realize the same transient performance. For more information on the opera-
tion of the coupled inductor topology, please contact Volterra.
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 (Lk) that would be required in an non-coupled topology
2. The rated current and peak current are based on Volterra’s testing of the
Pulse coupled inductors. For more information, please contact Volterra.
3. The open-circuit inductance per phase is measured inductance across
each phase (ie: measured at (1-2) or (3-4) or (5-6) or (7-8), when all
other windings are open) 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).
