PWER Power-One, Inc. (MM)

Power-One, Inc. (Nasdaq:PWER), a leading global manufacturer of renewable energy and energy-efficient power conversion and management solutions, announced today that it entered into a non-exclusive, worldwide, Field of Use agreement with Microchip Technology Inc. for Digital Power Technology (DPT) patents from Power-One.

Digital Power Technology drives increased system efficiency, improved design flexibility, faster time to market, decreased board space requirements and lower system costs. DPT also enables telemetry capability, providing access to critical information including current, temperature and voltage. Telemetry allows the system to accurately monitor its power consumption and thermal performance, enabling designers to easily engineer key features such as system power optimization, fault detection and predictive maintenance features into their end products.

Applications utilizing FPGAs, ASICS, DSPs continue to drive board densities higher, requiring complex power architectures to handle the increasing number of voltage rails and output voltages dropping below 1V. Digital Power Technology is an extremely effective solution for these complex power requirements.

"Power-One is pleased to license its Digital Power Technology to Microchip, a market leader in microcontrollers, and analog and mixed-signal semiconductors," said Steve Hogge President of Power Solutions business unit at Power-One. "With the increasing number of leading power supply and semiconductor companies partnering with Power-One, we continue to expand the market by providing energy-efficient technologies with increased functionality for our customers."

"These DPT patents support Microchip's goal of offering its customers a new level of performance and flexibility in analog-based, point-of-load power conversion solutions," said Bryan J. Liddiard, Marketing Vice President of Microchip's Analog and Interface Products Division. "Configurability through serial communication is crucial to system optimization and maximizing power conversion performance."
