Microprocessor voltage regulators and power supply trends and device requirements

Abstract

Summary form only given. This paper gives a general overview of microprocessor power regulators and supplies. Firstly, it covers the CPU power road map, thermal issues, current and voltage scaling and system constraints. Secondly, it outlines system operating parameters. Thirdly, it details buck regulator operation. Finally, it considers system level power supply trends, system chassis shrinking and power supply density.
