Keywords: PMBus digital power management power management protocol board designers
Until now, there has been no industry-wide consensus on digital power management. This has been the simple reason behind the increasingly complex design, configuration, control, and monitoring of power sources. By supporting the new PMBus protocol, many power supply and semiconductor manufacturers have taken a step towards a solution.This article examines how this new digital power management protocol introduces an unprecedented level of control flexibility for board designers. The discussion will focus on the advantages of the new system in low cost real-time control, its simple command language, flexibility, and in the ease of its implementation.
