Features

Specifications subject to change without notice.

Electrical specifications at 25˚C unless noted otherwise.

The ICL351-LS, a 3-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 ICL351-LS 3-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 cur-

rent System VRM (SVRM) applications where small size, high efficiency, and low total BOM cost is critical.
