Linear replacement solutions
CamSemi’s C2470 RDFC controllers offer SMPS performance for the price of a linear or less.
These novel devices control CamSemi's RDFC topology to create high efficiency, low cost SMPS solutions with uniquely low EMI for the replacement of linear power supplies in applications such as:
- cordless phones, mini adaptors, routers, wireless modems and other external AC/DC chargers/adaptors
- set-top boxes, audio and other products relying on embedded PSUs
C2471 products cover applications rated 1 to 6 W with C2472 and C2473 rated for 6 to 40 W (up to 60 W @ 230 V). Click to access the latest datasheets.

C2470 controllers beat ENERGY STAR requirements at the cost of a linear or less! |
Advantages:
- Cost effective solution - low system component count, simple circuits, fully optimised for high volume markets and low cost
- Energy-efficiency - high average efficiency and low standby power exceeds codes of conduct/regulations
- Low EMI – to meet FCC 68 and other standards with minimal components
- Naturally safe - high isolation & surge voltage withstand. No components sitting across high and low voltage sides of transformer and built-in safety features within the controller
Features:
- Highly integrated CMOS controller IC
- Drives low cost bipolar power transistors
- Resonant switching for high efficiency and low emissions
- Frequency optimised for power circuit parasitics
- IC protection for overload, over-temperature and under-voltage
Typical circuit for 6 to 40 W application
