In compact, portable, battery-operated devices, DC-DC converters are commonly used to provide the required internal voltages. Electrolytic and tantalum capacitors with low ESR (effective series resistance) are commonly used as power supply energy storage and filter capacitors. For the lowest possible ESR and highest capacitance, multiple devices are usually connected in parallel. The cost and the PC board area required are significant. cap-XX manufacturers supercapacitors that it believes provide designers with an alternative at reduced cost.
The use of a cap-XX supercapacitor can provide a single-device solution to energy storage and filtering. The components can be manufactured with a low ESR as well as a very high capacitance, if required, and they can be designed to suit the application, in shapes, sizes and packaging to fit the space available, such as thin prismatic forms. Where a higher capacitance can be used, the frequency of a DC-DC converter may be reduced without affecting ripple voltage.
