Cost vs Value
Confidential Information | © 2013 CUI Inc
Difficult to get to the value
Solution cost versus IC/Module cost Removal of additional components
for power management Reduced capacitance requirements

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.
