Product Details

The ADP5091 demonstration platform is a plug and play evaluation board (ADP5091-2-EVALZ) for energy harvesting. The evaluation board 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 ADP5091 energy harvesting power management IC.


The demonstration platform converts light energy to electrical energy. The PV panel converts the light to 0.8 V electrical energy. The ADP5091 boosts the input voltage from 0.8 V to 3.5 V and stores the energy in a supercapacitor.


The ADP5091 has a regulated output with programmable output voltage. By combining a low dropout (LDO) regulator and a boost regulator, it offers a more compatible output voltage than the output of a main boost regulator. 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 ADP5091 is an ultralow power, synchronous, boost dc-to-dc regulator. The ADP5091 runs from input voltages of 0.38 V to 3.3 V and provides a high efficiency solution with integrated power switch, synchronous rectifier, battery management, and one regulated output. The demonstration platform provides an easy way to evaluate the device.


Full details about the ADP5091 are available in the product data sheet, which should be consulted in conjunction with this user guide when using the ADP5091-2-EVALZ.


The system also plugs directly into the Analog Devices WSN demonstration platform.


This user guide UG-927 describes how to set up the board and how to use it for powering loads.
