CamSemi launches power range
Cambridge Semiconductor is launching a range of performance controller ICs that it says will enable power supply designers and volume manufacturers to develop more energy efficient products at lower cost than can be done with existing solutions.
The C2470 family is based on recent advances in intelligent digital/analogue control, coupled with a resonant single switch topology that has not previously been exploited in an integrated form for offline ac/dc power conversion. Operating efficiencies in excess of 80% are claimed, along with100 mW standby power consumption.
“Our goal is to enable energy efficient offline power conversion without a cost penalty and the C2470 family of controllers does just that,” said ceo David Baillie. “The devices have been specifically optimised for high volume, low cost, single rail input markets, offering double the efficiency over traditional linear supplies.”
