The NH2D0245 comes in a QFN package measuring 3mm by 3mm. Including the external capacitor it has an assembly footprint of just 3mm by 3.6mm. The NH2 is designed to extract the low power output of an energy harvesting source to charge a variety of energy storage elements such as a rechargeable battery or a super-capacitor. It is optimised for Solar PV (indoor and outdoor).
The NH2 is essentially a dc-to-dc converter that sits between the source and a capacitor. It has maximum power point tracking (MPPT) with an interval less than 1 second.
