GENERAL DESCRIPTION

The
ADP5090
demonstration platform is a plug and play
evaluation board (ADP5090-2-EVALZ) 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
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
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 Devices 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
ADP5090
is an ultra low power, synchronous, boost dc-to-dc
regulator. The
ADP5090
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
ADP5090
data sheet and must be consulted when using the

The demo platform system also plugs directly into the Analog
Devices

EVALZ
board and how to use it for powering loads.
