GENERAL DESCRIPTION
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 describes how to set up the board and how to
use it for powering loads.
