Power management integrated circuit with optimum power point evaluation

摘要

A power management integrated circuit (PMIC) is provided for extracting power from an energy harvester. The PMIC includes a power point tracker configured for defining an optimum operational voltage for efficiently extracting power from any type of energy harvesters such as electromagnetic energy sources, photovoltaic cells or thermal electric generators. The power management integrated circuit (PMIC) also relates to an energy harvesting system that includes an electromagnetic energy source and an impedance connected to the PMIC.
