CamSemi's latest mixed-signal controller is intended for use in the design of switched mode power supplies for cordless phone and other EMI-sensitive or low power consumer applications.

The C2471 is the latest addition to the C2470 family of controllers which are based on a patented resonant discontinuous forward converter (RDFC) topology that the company claims will maintain EMI clean resonant switching over the full load variation.

"This approach generates exceptionally low levels of EMI, whereas conventional flyback SMPS depends on fast, hard-edged switching that produces considerable emitted and conducted noise which can be difficult, time consuming and costly to filter out and overcome," said Simon McKay from Cambridge Semiconductor.
