Cambridge Semiconductor Limited

Cambridge Semiconductor Limited (CamSemi) is a fabless semiconductor business based in Cambridge, England that was acquired by US-based competitor Power Integrations Inc., in January 2015.
The company specializes in power management integrated circuits and was spun out of Cambridge University in August 2000 with seed investment from the Cambridge University Challenge Fund, as a commercial venture arising out of the research conducted by Professors Gehan Amarantunga and Florin Udrea at the Cambridge University Engineering Department.
CamSemi is developing a range of new ICs for use in power conversion products such as mains power supplies and lighting. The company’s products are enabling power supply manufacturers to develop low cost products that comply with Energy Star, the European code of conduct and related energy-efficiency regulations. All CamSemi products are based on a proprietary portfolio of technologies and topologies including advanced control architectures, RDFC and PowerBrane.
The company’s venture capital investors included DFJ Esprit, Scottish Equity Partners and cleantech investors The Carbon Trust and NES Partners.
