Power-One and Microchip Enter Into Patent License Agreement

CAMARILLO, Calif., May 7, 2013 (GLOBE NEWSWIRE) -- 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

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

"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."
