Power management ICs harvest energy

FUJITSU SEMICONDUCTOR MB39C811 dc-dc buck converter and MB39C831 dc-dc boost converter power management ICs utilize energy harvesting. Model MB39C811 provides a quiescent current of 1.5µA and achieves world-leading results in ultra-low power operation. Model MB39C831 includes a function that automatically responds to changes in the surrounding environment in order to store electrical power, such as harvesting power from light according to variations in ambient light as well as harvesting thermal power according changes in ambient temperature.
