The ADP5090 is an integrated boost regulator that converts dc power from PV cells or 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 cold startup, the regulator is functional at an input voltage range of 80 mV to 3.3 V. By sensing the input voltage at the VIN pin, the control loop keeps the input voltage ripple in a fixed range to maintain stable dc-to-dc boost conversion.
