Power
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.
