and addresses a real customer need for significant energy efficiency savings in the manufacture of power switching and rectifying components (AC/DC converters).”


Ian Watson, director of the aerospace, defence, security and space trade organisation, ADS Scotland, adds, “Today we see Raytheon UK gearing up for future success -through investment, collaboration and diversification. At ADS, we know one of the main challenges industry faces as it looks to the future is continuing technological discovery to stay ahead of global competition.”


“To address this challenge, it is vital that industry and academia work together to advance technology and fully explore commercial applications. Raytheon’s new facility at Glenrothes is a brilliant example of this and shows the company to be confident not only about its own future, but also the future of the United Kingdom as a home to market leading innovation.”


“This sector with companies such as Raytheon that operate in Scotland contributes billions in sales, millions in R&D and thousands in jobs. It demonstrates exactly why aerospace and defence are at the heart of the economy and why their success is crucial to our overall future economic prospects.”


Power supplies to drive semiconductor market


Although the global market for semiconductors used in power supplies is forecast to grow at a robust 6.5 percent in 2013, growth opportunities differ widely by semiconductor product and by applications


Despite a largely flat market for power supplies in 2012, IMS Research, (now part of IHS), predicts that the market will offer strong opportunities for some semiconductor manufacturers in 2013.


Its report, “The World Market for Semiconductors in Merchant Power Supplies - 2012,” analyses the opportunity for semiconductors in both the AC-DC and DC-DC power supply market and provides forecasts to 2016.


Apart from silicon, the main products used in power 186 www.compoundsemiconductor.net January/February 2013 applications are GaN and SiC.


Strongest growth is predicted for MPU/MCU/DSP/ DSC products at 35 percent in 2013.


Although this is currently one of the smallest markets for semiconductors used in power supplies, it is projected to grow by $45 million from 2012 to 2016 owing to adoption of digital power and advanced power factor correction (PFC) techniques.


Associate Director of IMS Research’s power management and conversion group, Ryan Sanderson, comments, “Demands for greater efficiency and increased power density continue to drive opportunities for semiconductor vendors. The market for digital power alone is forecast to quadruple in the next five years, as a direct result of this. Many more opportunities exist, however, linked to legislation and design changes.”


Other growth drivers include the increase in demand for power supplies which use synchronous rectification at the output, a trend projected to account for a large part of the $80 million growth forecast for the power MOSFET market from 2012 to 2017.


Also, the combined market for AC-DC switching regulators (integrated FET) and switching controllers (external FET) is predicted to grow by $270 million in the next five years. This is driven in part by demand for more intelligent solutions in cell phone chargers to cope with requirements for “no- load power consumption” and strong demand from applications such as tablets and LED lighting.


Sanderson adds, “2012 was a difficult year for many semiconductor vendors who sell into power supplies, with reduced demand from many sectors. Demand from end markets such as notebook PCs and industrial applications, which typically offer steady growth, was much weaker than average. Opportunities did exist, however, particularly in tablet PCs and the rapidly expanding market for LED lamps and luminaires. These opportunities are forecast to drive further growth in 2013 and beyond.
