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 dcto-dc boost conversion. The VIN OCV sensing and programmable regulation points of the input voltage allow extraction of the highest possible energy from the PV cell or TEG harvester. A programmable minimum operation threshold (MINOP) enables boost shutdown during a low light condition. In addition, the DIS_SW pin can temporarily shut down the boost regulator and is RF transmission friendly.The charging control function of ADP5090 protects rechargeable energy storage, which is achieved by monitoring the battery voltage with programmable charging termination voltage and shutdown discharging voltage. In addition, a programmable PGOOD flag monitors the SYS voltage.An optional primary cell battery can be connected and managed by an integrated power path management control block that automatically switches the power source from the energy harvester, rechargeable battery, and primary cell battery.The ADP5090 is available in a 16-lead, 3 mm × 3 mm LFCSP and is rated for a −40°C to +125°C junction temperature range.
