GENERAL DESCRIPTION
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.
The system also plugs directly into the Analog Devices WSN
demo platform.
This user guide describes how to set up the board and how to
use it for powering loads.
