APPLICATIONS
External AC/DC charger/adaptor (single voltage input) e.g. cordless phones, portable electric tools.
Embedded PSU (single voltage input) e.g. set-top boxes, DVD players, audio products, domestic appliances.
OVERVIEW
The C2472, C2473 and C2474 controllers use CamSemi’s Resonant Discontinuous Forward Converter
(RDFC) topology to create a high efficiency, low cost alternative to line-frequency transformer PSUs. By
operating in resonant mode, EMI is greatly reduced, enabling the replacement of linear PSUs in demanding
applications such as audio products and cordless phone chargers. The C2472, C2473 and C2474 controllers
also offer overload protection which is usually associated with more expensive switch mode solutions.
