ADP5090ACPZ-1-R7

The ADP5090ACPZ-1-R7 is an Ultralow Power Boost Regulator with MPPT and charge management that converts DC power from PV cells or TEG. 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. 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. 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.
