Implementing adaptive voltage scaling

Posted: 05 Nov 2014     Print Version  Bookmark and Share

Keywords:power dissipation  system on chip  SoC  adaptive voltage scaling  PMIC 

To optimise power dissipation and cut down junction temperature while achieving processing performance goals, various approaches are used to scale supply voltages to a system on chip (SoC) that contains several processors.

This application report details the nomenclature, summarises the parameters influencing power dissipation, and describes the implementation of one method known as adaptive voltage scaling (AVS). This report also describes how an optimised a power-management integrated circuit (PMIC), such as the TPS659038-Q1 device, can be used to implement this AVS method.
