About PMBus®

The Power Management Bus (PMBus) is an open-standard digital power management protocol: simple, standard, flexible, extensible, and easy to program for. The PMBus command language enables communication between components of a power system: CPUs, power supplies, power converters, and more.  For more information, please see this Introduction to PMBus.

Mission of PMBus®

PMBus standard adoption will make the world more energy efficient, one power supply at a time.
