    Business Editors/High-Tech Editors

    CAMARILLO, Calif.--(BUSINESS WIRE)--Jan. 13, 2005--Power-One, Inc. (Nasdaq:PWER) announced that their Z-One(TM) Digital Intermediate Bus Architecture (IBA) has been named a finalist in EDN Magazine's 2004 Innovation of the Year Awards. EDN will announce the winners on March 7th, at their 15th annual awards ceremony in San Francisco. This is the second 2004 industry-publication recognition for this advanced board-level power architecture. Last week, Power-One announced that they had won a Product of the Year Award from Electronic Products Magazine.
    Steve Goldman, Power-One's Chairman and CEO, commented, "I would like to thank EDN for naming Power-One as a finalist for this valued award. This recognition is another example of the widespread acceptance that has been gained since the on-time production release of the Z-One architecture in September. In addition to compelling technological advantages, we attribute this early success to an open-architecture strategy that provides customers with multiple-source availability and the capability to utilize industry-standard I2C bus communications protocols."
    Mr. Goldman continued, "Z-One Digital IBA is the first board-level power system to digitally integrate power conversion and power management, providing up to a 90% reduction in components, circuit-board traces, and development time. These advantages have earned us a number of design wins, and a high-level of interest in applications that are not traditional for Power-One; such as servers and data storage. Additionally, these benefits were some of the reasons why C&D Technologies chose to participate in the early adoption and licensing of the 'Z' technology in December."
    Z-One Digital IBA(TM) board-level power combines many innovative operating concepts to achieve an unprecedented level of power-system integration. A multitude of parameters, such as output voltages, sequencing, and warning signal limits are user-programmed through a graphical user interface, communicated through an I2C bus, and stored in the Digital Power Manager.
    At system startup, this stored information is used to initialize up to 32 programmable Z-Point-Of-Load (Z-POL(TM)) converters. After system initialization, ongoing communications between the Digital Power Manager, Z-POL converters, and host system support intelligent operation. This advanced architecture utilizes Power-One silicon and intellectual property, with dozens of patent applications supported by hundreds of claim elements.
