Overview

Digital Power Management provides a scalable and flexible mechanism for sequencing power supplies, monitoring voltage and current faults, and initiating shutdown under fault conditions. For example, the PMbus-based Digital Power Management derives its flexibility by adding digital communication and self monitoring capabilities to all on-board DC-DC Converters.

However, the vast majority of DC-DC converters available to most engineers are analog and do not include any of the monitoring and communication features.

This seminar shows how a centralized programmable power management IC could be used to implement most of the Digital Power Management features, while using analog DC-DC converters and LDOs. Design, QA, manufacturing, and test engineers could benefit from the associated communication and digital monitoring features, reducing overall cost of ownership.
