FEATURES
Plug and play energy harvesting platform
Compatible with Analog Devices, Inc., wireless sensor
network (
) platform
Solar panel harvester included
RoHS compliant
GENERAL DESCRIPTION
demonstration platform is a plug and play
evaluation board (
) for energy harvesting.
The demonstration platform 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
Devices™ PV cell, or the IXYS™ Corporation PV cell, and the
energy harvesting power management IC.
demonstration platform converts light energy to
electrical energy. The PV panel converts the light to 0.8 V
electrical energy. The
boosts the input voltage from
0.8 V to 3.5 V and stores the energy in a supercapacitor.
In addition, there is an on-board, low dropout (LDO) regulator
that powers loads at lower voltage rails than the 3.5 V stored in the
supercapacitor. The Alta Device
s
PV cell is a light harvesting
gallium arsenide-based cell. The PV cell is optimized for indoor
environments, where lux levels are typically 200 lux to 1000 lux.
The
is an ultra low power, synchronous, boost dc-to-dc
regulator. The
runs from input voltages of 0.38 V to
3.3 V and provides a high efficiency solution with an integrated
power switch, synchronous rectifier, and battery management.
The demo platform provides an easy way to evaluate the device.
Full details about the
devices are available in the
data sheet and must be consulted when using the
evaluation board.
The demo platform system also plugs directly into the Analog
Devices
demo platform.
This user guide describes how to set up the
board and how to use it for powering loads.
