ICE ICL651-2H

ICL651-2H
6-Phase VRD/POL Inductor
Applications
•VRDs (Imbedded)
•VRMs (Module)
•POLs
•VRM 10.x / VRM11 based designs
•DDR2/3 memory
Features
•Design for use with IKOR’s proprietary coupled inductor multi-phase DC-DC converter topology
•Low height and small size allows use in both imbedded (VRD) and module (VRM) applications
•Integrated design lowers cost and simplifies assembly
•Suitable for high temperature RoHS reflow processes
The ICL651-2H, a 6-phase inductor assembly using IKOR’s coupled inductor technology, solves the most pressing problem
facing IA-32 VRDs. This patented technology solves the trade-off between efficiency and 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 ICL651-2H 6-phase coupled inductor assembly is designed for VRD applications. Its integrated design
allows it 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.
