CamSemi has today announced recent advances in the company’s bipolar transistor drive scheme and the first of a new generation of Primary Side Sensing controllers to exploit these developments. The new C2172 PSS controller will enable manufacturers to develop what the company believes will be the industry’s lowest cost, most energy-efficient BJT-based solutions for mobile phone chargers and other universal input applications rated to 6.5 W.

CamSemi has launched the C2283, a novel high performance Primary Side Sensing flyback controller with a unique constant power mode. C2283 has been designed to offer fast load pull-up of electronic products with high input capacitance, such as modems and other networking devices, but is also ideal for set-top boxes and other high volume, energy-efficient universal input adapter applications rated above 8 Watts.

CamSemi has today announced a new Primary Side Sensing flyback controller that offers a significant reduction in system cost and component counts for higher power applications, as well as excellent light load and standby efficiency performance.

CamSemi has today announced the launch of the C3120 family of LED driver ICs and its intention to become a major player in one of the fastest-growing sectors of the lighting market. The new family has been specifically designed to drive an advanced boost/flyback topology to deliver the three essential performance requirements for volume LED applications: ‘best in class’ current regulation, high efficiency and power factor correction.
