Tyco Electronics Power Systems and SynQor announce Alignment with PMBus™ Initiative for Enhanced DOSA-Led On-Board Digital Power Management Architecture
DOSA-Led effort to enable Standard Digital Interfaces to On-Board DC/DC Power Converters
January 14 , 2005
Dallas, TX –Tyco Electronics Power Systems
(NYSE: TYC) and SynQor, the founding members of the Distributed-power Open
Standards Alliance (DOSA), announced an alignment with the Power Management
Bus (PMBus) initiative led by Artesyn Technologies Inc (NASDAQ: ATSN), and
a number of power-supply and semiconductor companies, as part of a larger DOSA-led
initiative to migrate to a digitally-interfaced, on-board DC/DC power architecture.
The DOSA architecture will include the PMBus protocol as well as new pinouts
and functionality defined in consultation with leading customers and DOSA members.
Also included will be standard software required to interface with the modules
over the industry standard I2C serial bus. These efforts will serve to migrate
the industry to a new digitally-interfaced power infrastructure in a measured
and low-risk manner, allowing customers to preserve their investment in existing
designs while moving to the benefits of a digital control interface.
“Digital interfaces to power modules will help reduce the design complexity
of on-board power that is being experienced by some of our customers today”,
said Sabi Varma, Vice President, Marketing and R&D, Tyco Electronics Power
Systems. “However, minimization of risk and ability to design in standard parts
with second-source capability remains a critical need for customers as well.
This effort will provide a graceful transition to Digital Interfaces while
preserving the considerable design expertise investment our customers have
made”.
“DOSA has endorsed and will adopt the Power Management Bus protocol in order
to reduce the uncertainty and maximize the benefit to our customers as they transition
to digital control, programming and monitoring of DC/DC modules”, said Joe Coupal,
Executive Vice President of Marketing and Sales, SynQor, Inc. “Our customers
want an open industry standard that will facilitate multiple, compatible product
sources. Current and emerging solutions only offer proprietary communication
formats. DOSA’s decision to adopt the PMBus protocol should solidify its position
as the de facto industry standard for power systems control.”
The DOSA-led efforts are expected to result in products in the second half of
2005 time frame. Standard enhanced pinout and functionality details are being
developed in cooperation with major customers and industry partners, and will
be released on the DOSA website as they are finalized.
DOSA was formed to ensure future DC-DC product compatibility and standardization.
The goal of the alliance is to establish standards over a broad range of power
converter form factors, footprints, feature sets and functionality for point-of-load
(POL) and isolated applications. For further information, visit the DOSA website
