Advanced PMICs Can Flatten The Processor Power Curve For Data Centers

Focus:

With data center operators under pressure to keep energy consumption and costs to a minimum, they are looking for the most efficient ways to address increased power demands and to break the linear relationship between increased processor power and increased rack power. This article discusses a new family of power management ICs from Empower Semiconductor—highly integrated voltage regulator ICs (IVRs) that switch at frequencies in the low hundreds of megahertz— and how they can be used to reduce processor power consumption by implementing dynamic voltage scaling (DVS). The power and size reduction benefits of the IVRs and DVS are discussed in a typical DSP application. Article includes data on data center and server rack power consumption.

What you’ll learn:

• How to understand the space and power saving benefits of using Empower Semiconductor’s integrated voltage regulators (IVRs)
• How to reduce processor power consumption using dynamic voltage scaling
