Intersil drives power MOSFET tech with Great Wall buyout

Intersil has announced that it will acquire Great Wall Semiconductor, a company that focuses on power MOSFET technology for cloud computing, space and consumer applications, particularly citing lateral power MOSFET expertise and IP.

Intersil comments that GWS's design team brings valuable experience in advanced design and process technology to enable power efficiency gains and footprint reduction in complex power systems. GWS's existing and emerging FET products, in combination with Intersil's power controller portfolio, are expected to expand Intersil's addressable market and provide compelling integration opportunities to accelerate innovation in the development of next-generation power stages.

"This small but experienced team will be a great asset as we continue to expand our power management capabilities," said Mark Downing, senior vice president of corporate strategy and infrastructure power products. "Intersil's strategy is based on establishing market leadership through the development of highly efficient and highly integrated power management solutions."

Last year, Intersil announced that it would ramp up its design centres in the United States and United Kingdom as it closed down most of its analogue products to concentrate on power management. One year after joining from Silicon Labs, the company's president and CEO Necip Sayiner had significantly changed the company's focus.

"What we found when we came in was capable people and some great fundamental IP but they were trying to do too many things they didn't have the resources to drive leadership, develop new products and translate that into market share," said Downing. "So we are focusing on our core strengths around power management."

Power is 60 per cent of Intersil's business and that will rise to 80 per cent over the next three years, he added.

Lateral Power MOSFET

"GWS has differentiated itself through expertise in Lateral Power MOSFET device and processing technology combined with miniature chipscale packaging," said Sam Anderson, CEO of Great Wall Semiconductor. "We have developed important intellectual property that enables energy savings and environmental progress that can now reach a broader set of customers and markets as we become part of Intersil."

Intersil acquired GWS for initial cash consideration of $19 million, with up to $4 million additional cash consideration based on the achievement of post-closing business metrics through 2016.

Great Wall Semiconductor was founded in 2002, and has 10 employees. GWS has been awarded 22 patents related to lateral low voltage power MOSFET technology. The technology has been successfully deployed to enable efficient power conversion in cloud computing, space and mobile applications.
