ADP5090-2-EVALZ: 3.5V @ 800mA, 0.8 ~ 3.3V in

Summary

The ADP5090 demonstration platform is a plug and play evaluation board (ADP5090-2-EVALZ) for energy harvesting. It includes the photovoltaic (PV) panel and all of the power management to enable devices to be powered using energy harvesting. It is based on the Alta Device PV cell and the ADP5090 energy harvesting power management IC.

The ADP5090 demonstration platform converts light energy to electrical energy. The PV panel converts the light to 0.8 V electrical energy. The ADP5090 boosts the input voltage from 0.8 V to 3.5 V and stores the energy in a supercapacitor.

In addition, there is a low dropout (LDO) regulator on board that powers loads at lower voltage rails than the 3.5 V stored in the supercapacitor. The Alta Device PV cell is a light harvesting, dye sensitized PV cell. It is optimized for indoor environments, where lux levels of 200 lux to 1000 lux are typical.

The ADP5090 is an ultralow power, synchronous, boost dc-to-dc regulator. The ADP5090 runs from input voltages of 0.38 V to 3.3 V and provides a high efficiency solution with integrated power switch, synchronous rectifier, and battery management. The demo platform provides an easy way to evaluate the device.

Full details about the parts are available in the ADP5090 data sheet, which should be consulted when using the ADP5090-2-EVALZ.
