Ultra-Low-Power Boost Regulator with MPPT and Charge Management

The charging control function of ADP5090 from ADI protects rechargeable energy storage

Image of ADI's Ultralow Power Boost RegulatorADI'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 16 μW to 200 mW range with sub-μW operation losses. With the internal cold-start circuit, the regulator can start operating at an input voltage as low as 380 mV. After a cold start-up, the regulator is functional at an input voltage range of 80 mV to 3.3 V.
