PMBus™: The Power System Standard

The Power Management Bus (PMBus) is an open
standard power-management protocol with a fully
defined command language that facilitates communication with
power converters and other devices in a power system. The
protocol is implemented over the industry-standard SMBus serial interface and enables programming, control, and real-time monitoring of compliant power conversion products. This flexible and highly versatile standard allows for communication between devices based on both analog and digital technologies, and provides true interoperability which will reduce design complexity and shorten time to market for power system designers. Pioneered by leading power supply and semiconductor companies, this open power system standard is maintained and promoted by the PMBus Implementers Forum (PMBus-IF), comprising 30+ adopters with the objective to provide support to, and facilitate adoption among, users.

The PMBus-IF is part of the System Management Interface Forum (SMIF), Inc., a nonprofit industry standards group.
