LONDON Cambridge Semiconductor Ltd. (CamSemi) has extended its C round funding to bring the total sum raised to $34 million (about £17 million) with an $8 million (about £4 million) equity stake from BankInvest Group (Copenhagen, Denmark) through its New Energy Solutions venture capital fund.
The initial C round investment was announced in October 2007 and included funds from Carbon Trust Investments in the round led by 3i and existing shareholders Scottish Equity Partners (SEP) and TTP Ventures.
“BankInvest is actively investing to help bring more energy-efficient, sustainable technologies to market and is delighted to add CamSemi to our growing portfolio,” said Jens Christian Mathiesen, senior partner at BankInvest New Energy Solutions.
CamSemi (Cambridge, England) is developing ICs that will allow manufacturers to introduce 'cost-efficient' mains-connected converters and battery chargers that are smaller, cheaper and more power efficient than existing wasteful solutions.
The company’s first products were introduced at the end of last year and lower cost, more efficient supplies for high volume consumer products are now in full-scale production.
The C2471 was launched in April and allows designers to meet the demands of FCC part 68 standard for telecommunication equipment and ENERGY STAR 2.0 for energy-efficiency but without needing costly, complex filtering circuitry or specialist design skills. This controller targets high volume, consumer applications rated at one to six watts including household telecommunications and audio equipment.
The controllers are based on a patented resonant discontinuous forward converter (RDFC) topology that maintains ‘EMI clean’ resonant switching over the full load variation. This approach generates exceptionally low levels of EMI. Conventional flyback SMPS depends on fast, hard-edged switching that produces considerable emitted and conducted noise which can be difficult, time consuming and costly to filter out and overcome.
BankInvest New Energy Solutions venture fund was established in 2002 by the BankInvest Group. Its two funds of more than &euro 150 million (about $ 234million) are dedicated to cleantech and energy solutions with a geographical focus on Scandinavia, Europe and North America.
