CamSemi develops low cost solution for offline applications above 8-W
C2183 is ideal for universal input charger and adapter applications such as SOHO switches, routers and other networking products rated above 8 W that require high performance voltage and current regulation. Other target applications include media tablets, set-top boxes and power tools.
C2183’s light load performance will enable manufacturers to more easily meet the 50% reduction in product standby power consumptions required by EC 1275/2008 tier two – as well as any increased efficiency requirements potentially resulting from the US Department of Energy’s current rulemaking review – but with system-level costs that are lower than all current competitive approaches. CamSemi’s new PSS controller also requires fewer and lower cost components elsewhere on the board and operates at up to 100 kHz to further shrink product form factors.
C2183 incorporates many of the same key design benefits of CamSemi’s novel PSS technology that have helped the company to secure multiple design wins in its core markets and to become a leading supplier to many of the world’s top networking and consumer electronics brands. Features include: highly accurate current and voltage regulation; quasi-resonant switching to improve efficiency and reduce EMI; ‘best in class’ load-transient performance requiring minimum output capacitance; and a full set of protection features.
Samples of C2183 in a SOT23-6 package are available now and a product datasheet can be downloaded from www.camsemi.com/datasheets
