Fujitsu Releases Two New Energy Harvesting Power Management IC Products


Fujitsu Semiconductor Europe (FSEU) today announced the release of two new power management IC products developed to utilize energy harvesting, the MB39C811 DC/DC buck converter and the MB39C831 DC/DC boost converter.

The MB39C811 buck converter features a quiescent current of just 1.5µA and achieves world-leading results in ultra-low power operation. Moreover, the MB39C811 represents the world's first simultaneous use of energy generation from both light and vibration using only one power management IC device.

The MB39C831 boost converter 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. This function enables the unit to store energy harvested from the different elements at very high levels of efficiency.

Deploying these new products will contribute to new battery-free technologies in areas such as energy management for homes and buildings as well as wireless sensor networks for farms, and will also lead to longer battery lives for portable devices. The full story is available from 

We invite UK businesses and researchers to join the UK Energy Harvesting Mission to Japan which offers an excellent opprtunity to meet Fujitsu and other companies at the Techno-Frontier 2013 (16-19 July 2013, Tokyo, Japan).
