SiliconReef has announced its first product, the EH01, a complete power management solution for a variety of energy-harvesting applications, providing a small and simple solution combining power from different sources: a dc wall adapter, photovoltaic cells and a Li-Ion battery. This device enables a simple implementation of a 5V supply, like a USB charger compatible with the ITU standard for the Universal Charging Solution (L.1000). The chip is packaged in a 20 contact 5mm by 5mm QFN package.

Using a high efficiency dc-dc converter the EH01 converts the voltage from the panel to a stable 5V output. In addition a Li-Ion Battery Charger (with numerous protection features) stores the excess energy from the panel in an external battery. This battery then complements the energy to the dc-dc converter when needed.
