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.

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.   Table 2.

J4 Output Connector Rev. 0 | Page 5 of 9 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). UG-927 ADP5091-2-EVALZ User Guide 14167-004 EVALUATION BOARD SCHEMATICS 14167-113 Figure 13.
