CamSemi offers two product families for low cost, energy-efficient adaptors for networking products, such as hubs, modems and routers.

C2163 PSS flyback controller

• Low cost universal input solution for 8 to 20 W applications
• Excellent light load efficiency to meet EC regulation 1275/2008
• Low standby power consumption for modem/router
• +/- 5% CV without board-level trimming
• Quasi-resonant switching reduces EMI for easier FCC 68 compliance
• Bipolar primary switch cuts costs and EMI components required
• Capacitive load pull-up
• Complies with ETSI-12W-CPS for hold-up time (‘dying gasp’)
• Programmable maximum switching frequency
• Low component count

C2471/C2472 RDFC controllers

• Single-rail input for 0 to 6 W (C2471) and >6 W applications (C2472)
• Excellent light load efficiency to meet EC regulation 1275/2008
• >85% energy efficiency
• Exceptionally low EMI for easy FCC 68 compliance without extra components
• High isolation and surge voltage withstand
• SMPS features and performance at the price of a linear or less
