Features

  • Converter can operate from a single-cell supercapacitor and deliver 40 W of output power
  • Operates down to 1.5-V input voltage enabling deep discharge of a supercapacitor
  • Cost-effective design using a non-synchronous controller
  • Starts up from as low as 1.5 V
  • Design has been built and tested
