RDFC topology
The Resonant Discontinuous Forward Converter (RDFC) is a novel topology delivering considerable technical and commercial benefits when coupled with CamSemi’s C2470 family of mixed signal controllers.
Advantages include:
- Low cost components, small transformers and simple designs covering a wide power range
- Low EMI
- High efficiency
- Low standby power
- Safety features from both the topology and the controller
- Small footprint transformers to reduce the demand for copper and steel [click the image to review the latest copper price].

Transformers are tiny: reducing demands for copper, steel & other raw materials |
The approach is aimed primarily at linear replacement in a wide variety of applications such as plug-top adapters, embedded supplies and battery chargers. As well as being cost effective and with extra safety features built-in, RDFC enables easy, fast compliance with new regulations on efficiency and standby power including ENERGY STAR 2.0.
Typical circuit covering wide range of powers from 6 W to 40 W
