What are the key features of ADP5090ACPZ?
- Integrated maximum power point tracking (MPPT) with programmable open-circuit voltage ratio maximizes energy extraction from solar cells and thermoelectric generators
- Operates from input voltages as low as 100 mV, enabling startup from weak ambient energy sources such as indoor photovoltaic panels below 10 lux
- Combined boost regulation and battery/supercapacitor charge management in a single IC reduces BOM and board area for energy-harvesting designs
- Ultralow quiescent current in the sub-µA range extends harvest cycles in duty-cycled wireless sensor nodes
- Flexible output voltage programmable up to 3.3V or higher supports a wide range of microcontrollers and radio transceivers in batteryless IoT systems
What is ADP5090ACPZ used for?
The ADP5090 is optimized for wireless sensor nodes and IoT edge devices that harvest energy from photovoltaic cells, thermoelectric generators, or piezoelectric transducers. Its 100 mV cold-start capability and integrated MPPT enable maintenance-free operation in building automation sensors, environmental monitoring nodes, and industrial condition-monitoring tags where replacing batteries is impractical.

Frequently Asked Questions
What is the minimum input voltage the ADP5090ACPZ can start from and what energy sources does this support?
The ADP5090ACPZ can cold-start from input voltages as low as 100 mV, enabling energy harvesting from weak sources such as small indoor photovoltaic panels producing below 1 mW, single-cell thermoelectric generators with temperature differentials as small as 5°C, and piezoelectric cantilevers in low-vibration environments.
How does the MPPT function in the ADP5090 improve energy extraction compared to a fixed-input regulator?
The ADP5090 implements MPPT by periodically sampling the open-circuit voltage of the source and setting the operating point to a programmable fraction (typically 50–80%) of that voltage. This approach can increase harvested power by 20–40% over a fixed operating point when source impedance varies with illumination or temperature, improving overall system runtime on a 100 µF supercapacitor reservoir.
Which storage elements does the ADP5090 support and what charging voltages can be programmed?
The ADP5090 supports both supercapacitors and rechargeable thin-film batteries as primary energy storage. The charge termination voltage is programmable via external resistors, accommodating supercapacitor stacks up to approximately 4.2V and thin-film lithium batteries requiring a 3.8V or 4.0V charge termination, all managed by the on-chip charge controller.
How does the 20-pin QFN package of the ADP5090ACPZ benefit PCB layout in space-constrained IoT sensor nodes?
The 20-pin QFN package measures 4 mm × 4 mm with a 0.5 mm pin pitch, providing a compact footprint that allows the complete energy-harvesting power stage — including the boost inductor, storage capacitor, and ADP5090 — to fit within a 1 cm² area on a wireless sensor node PCB. The exposed pad also improves thermal dissipation at the up to 100 mA output current levels.
