Ultra low-power boost regulator features MPPT and charge management

Now stocked by Digi-Key, ADI's ADP5090 is an integrated boost regulator that converts DC power from photovoltaic (PV) cells or thermoelectric generators (TEGs). The device charges storage elements such as rechargeable Li-Ion batteries, thin film batteries, super capacitors, and conventional capacitors, and powers up small electronic devices and battery-free systems. The ADP5090 provides efficient conversion of the harvested limited power from a 16µW to 200mW range with sub-µW operation losses. With the internal cold-start circuit, the regulator can start operating at an input voltage as low as 380mV. After a cold start-up, the regulator is functional at an input voltage range of 80mV to 3.3V.
