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 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 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 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 ADP5090 devices are available in the ADP5090 data sheet and must be consulted when using the ADP5090-2-EVALZ evaluation board.
The demo platform system also plugs directly into the Analog Devices WSN demo platform.This user guide describes how to set up the ADP5090-2-EVALZ board and how to use it for powering loads.
