IRVINE, Calif., June 8, 2009 (GLOBE NEWSWIRE) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog mixed signal integrated circuits and high reliability semiconductors, today announced that it has executed an asset purchase agreement with Nexsem, Inc., a small privately held semiconductor designer and marketer based in Orange County, CA.

Nexsem is a growing designer and marketer of high voltage DC to DC conversion devices targeted at the traditionally fast growing commercial markets such as the: LCD-TV, Set Top Box, Notebook and Netbook, and other high-volume commercial applications.

"In Nexsem we have found an excellent complement to our existing power management offerings," stated James J. Peterson, President and Chief Executive Officer of Microsemi Corporation. "Focusing on higher power 5 to 40 watt applications, Nexsem's impressive technology nicely supplements our industry-leading low power product offering, while increasing our total dollar content per application in several high-growth markets. Not only is this strategic for our Analog Mixed Signal product offering, but it demonstrates our continued focus on a balanced growth model at Microsemi; one which augments the steady nature of our High-Reliability markets with the traditionally high growth opportunities found in the commercial marketplace."

Microsemi will further discuss this acquisition and provide general business updates during its third quarter results conference call in July 2009.
