Taking a system-oriented approach to board-level power management

Keywords:power management  board level power  systems oriented approach 

As circuit board assemblies encompass increasing numbers of sub-systems, their power distribution and management systems experience corresponding increases in complexity. As these systems become more sophisticated, traditional fixed-function hardware-focused power management schemes rapidly become unwieldy.

An alternative is to tackle the design problem with a top-down, requirements-driven approach. Instead of trying to design the board's power management functions around one or more fixed-function ICs, the designer defines the system in terms of individual physical and logical functions, and allows those to drive the design. Designing in this way requires a radical departure in design philosophy, where much of the system's control logic is shifted from hardware into firmware or software. The advantages, however, include lower component count, lower system cost and more flexibility in accommodating unforeseen requirements.

This article describes an example of this system-oriented approach applied to CompactPCI (cPCI) board-level power management, including hot swap capability.
