Microchip Technology's Pure Sine Wave Uninterruptible Power Supply (UPS) Reference Design Demonstrates Digital Power Advantages


Reference Design Showcases Lower Cost, Smaller Size, Greater Efficiency and Programmability of Implementing UPS With Digital Power

CHANDLER, Ariz., July 22, 2009 [NASDAQ: MCHP] - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced its Pure Sine Wave Uninterruptible Power Supply (UPS) Reference Design, which is based on the dsPIC33F "GS" series of digital-power Digital Signal Controllers (DSCs). This reference design demonstrates how digital-power techniques-when applied to UPS applications-enable easy modifications through software, the use of smaller magnetics, intelligent battery charging, higher efficiency, compact designs, lower audible and electrical noise via a purer sine-wave output, USB communication and a lower overall bill-of-materials cost. Though not available for purchase, all of the documentation, software and Gerber files needed to build this reference design can be obtained for free from Microchip's Web site at: www.microchip.com/offlineups. Additionally, demonstration units are available from the Company's field sales force.
