In a non-coupled multi-phase topology, the power supply sees the same induc- 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 contact Volterrra. 2.The rated current per phase is based on Volterra's testing of the Pulse coupled inductors. 3.The magnetizing inductance per phase is the measured inductance (at 0Adc) across each phase when all other phases are open-circuit. This inductance is a Pulse production measurement. Although the equivalent inductance per phase during steady-state is significantly higher then the equivalent transient inductance as listed, it should not be confused with the magnetizing inductance. 4.The magnetizing inductance per phase is the measured inductance (at 5Adc) across each phase when all other phases are open-circuit. This inductance is a Pulse production measurement. This test is performed to verify that the inductor can withstand a phase-to-phase load imbalance of 5Adc without saturating. 5.The nominal value of DCR/phase is for reference only. For production testing, the maximum limit is used. 6.The VT1105M ® and VT1115M ® are registered trademarks of Volterra Semiconductor Corporation.
