SMT POWER INDUCTORS Power Beads - PA131xNL Series Coupled Inductors Two, three, four and five phase Coupled Inductors for VR10/VR11 applications For use only with Volterra VT1105M ®, VT1115M ® 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 Faster transient response due to the ability to use lower effective inductance values Reduced overshoot/undershoot during load transients Frequency range up to 2MHz Electrical Specifications @ 25°C — Operating Temperature -40°C to +130°C Pulse Part No. Number of Coupled Phases Equivalent1 Transient Inductance per Phase (nH) Irated2 per Phase (Adc) Magnetizing Inductance per Phase3 nH ±20%, 0Adc L1 L2 L3 L4 L5 (1-2) (3-4) (5-6) (7-8) (9-10) Magnetizing Inductance per Phase4 nH MIN, 5Adc L1 L2 L3 L4 L5 (1-2) (3-4) (5-6) (7-8) (9-10) DCR/Phase5 (mΩ) TYP MAX PA1312NL 2 50 40 310 310 - - - 240 240 - - - PA1313NL PA1314NL 3 4 50 40 370 450 370 - - 285 350 285 - - 0.425 0.5 50 40 370 490 490 370 - 285 385 385 285 - PA1315NL 5 50 40 370 470 490 470 390 285 365 385 365 285 NOTES: 1. 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 pe...
