Alliance to adopt PMBus interface

Edited by the Electronicstalk editorial team Dec 6, 2004

The members of the POLA alliance are to jointly design and release products in accordance with the PMBus digital interface and control specification during 2005.

The POLA alliance announced today that it will jointly design and release products in accordance with the PMBus digital interface and control specification in 2005.

PMBus will allow advancements and flexibility in power conversion products without increasing complexity for the end user.

Members of the POLA alliance intend to release completely interoperable digitally controlled products in 2005.

These products will offer advanced features allowing end users to revolutionize their power management.

The PMBus is a working group consisting of several power and semiconductor companies that aims to release an open protocol supporting communication to power supplies via a digital bus.

Point of load (PoL) regulators allow more design flexibility when there are many voltages present in the same system.

PoL devices are particularly useful in complex circuits such as those incorporating ASICs and DSPs that demand power sequencing.

Companies forming the POLA alliance are Texas Instruments, Artesyn Technologies, Astec Power of Emerson Network Power and Ericsson Power Modules.

Customer demand for multiple sources led the formation of the alliance and standards.

POLA is the only alliance that offers completely interoperable products.
