Abstract

The manufacturers of electronic devices are constantly searching for efficiency improvements in point-of-load (POL) devices. To address that need, techniques are presented herein that support using low-cost graphite powder to improve inductor series resistance and conductivity. Under aspects of the presented techniques, multi-layer graphene may also be used to achieve significantly higher efficiency gains. It is anticipated that application of the presented techniques will yield a nominal gain of between 0.1% and 0.2%, which is significant when such a solution is applied to the many POLs that reside within a single design and across the millions of units that are sold.
