Power delivery for the next generation mobile platform

Power delivery has become a key element for the mobile platform to improve battery life and meet the energy star requirements. In this abstract, we will show innovative modeling and design techniques to improve the energy efficiency of the mobile platform power delivery subsystem. These techniques includes better modeling of the on die voltage distribution and optimizing the power delivery subsystem by optimizing for the light load. We will also show measurements of typical systems demonstrating the need for drastic improvements in the notebook power delivery in the next few years.
