Cambridge Semiconductor Ltd. (Cambridge, England) is older than Powervation having been formed in 2000. Its latest product is the C2283, a primary side sensing controller with a constant power mode for flyback power supply designs. The C2283, which offers fast voltage pull-up is suitable for electronic products with high input capacitance, such as modems and other networking devices, but is also for set-top boxes and other high volume, energy-efficient universal input adapter applications rated above 8 Watts, the company reckons.
The C2283 helps manufacturers meet the standby power requirements of EC 1275/2008 tier two. EC 1275/2008 is the European Commission’s eco-design regulations covering energy efficiency requirements for products with standby and/or off modes came into force in January 2010. The rules apply to any IT equipment intended primarily for domestic use, as well as almost all domestic appliances and other consumer products.
After 12 years CamSemi, as the company is known, is still privately held but there is some evidence that the company is starting to prosper as digitally controlled power comes of age. The company was listed as one of the fastest growing technology-based companies in the United Kingdom. Its annual sales increased by 85 percent a year from £1 million (about $1.6 million) in 2008 to about £6.5 million (about $10.5 million) in 2011.
And from the old to the new Amantys Ltd., also headquartered in Cambridge, was founded in 2010 by a group of former ARM executives with a vision to apply digital control to high power electronics. It is not trivial but the company is starting to offer products that claims will allow systems to have greater efficiency, better reliability and reduced cost.
The other thing to note is that all three companies have, at one time or another, been members of the Silicon 60, EE Times' list of emerging technology startups.
