CamSemi offers a range of controllers and circuit topologies – including the company’s unique RDFC approach - for low cost, chargers and adapters for audio products.

RDFC is perfect for AM radios and other EMI-sensitive applications. 

C2161/C2162 PSS controllers offer:

  • Low cost universal input solution for applications up to 8 W
  • Very low standby power consumption
  • Exceeds Energy Star 2.0 and European code of conduct v4 efficiency requirements
  • +/- 5% CC/CV without board-level trimming
  • Quasi-resonant switching significantly reduces EMI and cuts filter components
  • Significant design and manufacturing flexibility

C2471/C2472 RDFC controllers offer:

  • Single-rail input for 0 to 6 W (C2471) and >6 W applications (C2472)
  • >85% energy efficiency
  • <150 mW typical standby power consumption
  • Unique soft-switching resonant waveform
  • Easily meets EN550022 for AM compliance with >30dB quasi-peak margin on conducted emissions
  • No need for expensive common-mode filter components, even at higher powers
  • SMPS performance at the price of a linear or less
