Limited credit, jittery customers, and currency fluctuations have severely hit PV (photovoltaic) vendors. Thu, 22 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6702281.html?rssid=237 Last year, EDN's power supplement discussed the still-young digital-power market in terms of overall market potential for digital controllers. Digital power has now matured to the point at which Gartner breaks out products by application type. Thu, 22 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6702280.html?rssid=237 Reflecting the worldwide economic recession, the semiconductor industry last year showed its first revenue drop since 2000. However, although total semiconductor-industry revenue for 2008 declined by 5.4% to $255 billion, the market for power-management ICs grew 1% from $8411 million to $8473 million. Thu, 22 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6702279.html?rssid=237 Power transistors and diodes are the workhorses of the semiconductor industry: Without them, you cannot move or transform any significant amount of electrical energy. The servers populating enormous data farms, white goods with their newly efficient motors, hybrid-electric cars, and home theaters rely on power transistors and diodes that switch and manage their power requirements. Thu, 22 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6702278.html?rssid=237 Last year was the first since 2000 that the semiconductor industry’s revenues dropped. The power-management-IC segment, however, bucked the trend by eking out a 1% gain. Likewise, the decidedly unglamorous power-transistor and -diode segment, already at almost $15 billion, promises to continue to grow.

Thu, 22 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6699802.html?rssid=237 Government agencies and utilities are pushing to move the global power infrastructure to a smart grid—a transition that will rely on the installation of intelligent power meters in residences and businesses. Tue, 06 Oct 2009 00:00:00 PDT http://www.edn.com/article/CA6694955.html?rssid=237 Osram Opto Semiconductors announced lab results for a direct-emitting green-InGaN (indium-gallium-nitride)-laser diode. In pulsed-mode operation at room temperature, the laboratory prototype achieved an optical output of 50 mW, with a threshold-current density of approximately 9 kA/cm2, emitting light in true green—defined by the spectral range of 515 to 535 nm—with a wavelength of  515 nm. Thu, 17 Sep 2009 00:00:00 PDT http://www.edn.com/article/CA6694946.html?rssid=237 By understanding the stages of an analog-signal path, digital-system developers can more accurately capture sensor data for a variety of applications.
