Evaluation Board for the ADP5091 Demonstration Platform for Energy Harvesting
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.
FEATURES
Plug and play energy harvesting platform
Compatible with Analog Devices, Inc., wireless sensor
network (WSN) platform
Solar panel harvester included
One regulated output with programmable output voltage
RoHS compliant
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.
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.
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 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 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.

EVALUATION BOARD HARDWARE
J2
The ADP5091 has an additional regulated output containing an
LDO and a boost. On this evaluation board, the boost is always
shut down. With the options of different resistor values, the
LDO can generate different output voltages. Table 1 shows the
jumper connections and the corresponding output voltage on
the ADP5091-2-EVALZ. See the Evaluation Board Schematic
section for more details.

J4 OUTPUT CONNECTOR
A detailed description of each J4 output connector pin follows:
The J4 output connector (see Figure 12) connects the evaluation
board to the load. In addition to providing power, J4 also provides
other interface connections that allow more interaction between
the evaluation board and the host microcontroller unit (MCU)
on the load. The evaluation board is directly compatible with
the Analog Devices WSN demonstration boards. Table 2 shows
the pinout of the J4 output connector and a brief description of
the pin functions.

The VOUT pin (Pin 1) is the output voltage that the
evaluation board delivers to the load.
The ADP5091 has a programmable PGOOD signal. When
the PGOOD threshold is reached, the ADP5091 sets the
PGOOD pin (Pin 2) high. It is connected to the host MCU
general-purpose input/output (GPIO) input. See the
ADP5091 data sheet for more detailed information on this
function.
The GND pin (Pin 3) is the ground connection for the
ADP5091.
Connect the DIS_SW pin (Pin 4) to the host MCU GPIO
output. If the host MCU requires the ADP5091 to
temporarily halt the switching regulator function, set this
pin high. Remove the J1 jumper at the same time, if this
function needs to be used. See the ADP5091 data sheet for
more detailed information on this function.
Connect the BATT pin (Pin 5) to the analog input of the
host MCU to monitor the voltage on the supercapacitor of
the ADP5091-2-EVALZ. Populating R17 and R21 creates a
resistor divider for cases where the MCU analog input
range is lower than the supercapacitor voltage.
The EN pin (Pin 6) is the enable control signal for the
regulated output. Connect this pin to the host MCU GPIO
output to enable or disable the LDO. Also remove R25 if
this function needs to be used.
Connect the BACK_UP pin (Pin 7) to the analog input of
the host MCU to monitor the voltage on the backup
battery of the ADP5091-2-EVALZ. Populating R16 and
R20 creates a resistor divider for cases where the MCU
analog input range is lower than the supercapacitor voltage.
The REG_OUT pin provides an additional output with a
different voltage than VOUT when VOUT is using bypass
mode (see Table 1).
