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
