The ICL 701-1 using IKORâs coupled inductor technology solves the most pressing problem facing IA-32 VRDs
and VRMs. This patented technology solves the trade-off between efficiencyand elimination of bulk capacitors
by dramatically lowering the VRM output inductance while using industry-standard components and relatively
low switching frequencies. This technology provides superior transient response performance to higher
frequency solutions due to the unique method of coupling between phases, and enables high-current designs
with little or no electrolytic output bypass capacitance. The ICL701-1 coupled inductor can be used in both
VRD and module VRM applications. Its small size and low height make it possible to design high-density VRMs
and to fit the inductors very close to the CPU socket in VRD applications. This device can also be used in high-
current System VRM (SVRM) applications where small size, high efficiency, and low total BOM cost is critical.
