PMBus Interoperability

Confidential Information | © 2013 CUI Inc

InteroperabilityThe IEEE Glossary defines interoperability as, the ability of two or more systems or components to exchange information and to use the information that has been exchanged.

Confidential Information | © 2013 CUI Inc

The Power Management Bus (PMBus) is an open standard power-management protocol with a fully defined command language that facilitates communicationwith power converters and other devices in a power system.

Digital Power Controller 2.0

Second Serial Bus

With the requirements of a higher speed bus for advanced features, customer requests to reduce traffic on the SMBus, and the need to differentiate, many digital controllers have introduced a 2nd, separate single wire bi-directional serial bus.
