Product Details

The ADP5090 is an integrated boost regulator that converts dc power from PV cells or TEGs. The device charges storage elements such as rechargeable Li-Ion batteries, thin film batteries, super capacitors, and conventional capacitors, and powers up small electronic devices and battery-free systems.

The ADP5090 provides efficient conversion of the harvested limited power from a 16 µW to 200 mW range with sub-µW operation losses. With the internal cold-start circuit, the regulator can start operating at an input voltage as low as 380 mV. After cold startup, the regulator is functional at an input voltage range of 80 mV to 3.3 V.

By sensing the input voltage at the VIN pin, the control loop keeps the input voltage ripple in a fixed range to maintain stable dcto-dc boost conversion. The VIN OCV sensing and programmable regulation points of the input voltage allow extraction of the highest possible energy from the PV cell or TEG harvester. A programmable minimum operation threshold (MINOP) enables boost shutdown during a low light condition. In addition, the DIS_SW pin can temporarily shut down the boost regulator and is RF transmission friendly.

The charging control function of ADP5090 protects rechargeable energy storage, which is achieved by monitoring the battery voltage with programmable charging termination voltage and shutdown discharging voltage. In addition, a programmable PGOOD flag monitors the SYS voltage.

An optional primary cell battery can be connected and managed by an integrated power path management control block that automatically switches the power source from the energy harvester, rechargeable battery, and primary cell battery.

The ADP5090 is available in a 16-lead, 3 mm × 3 mm LFCSP and is rated for a −40°C to +125°C junction temperature range.

View Detailed Evaluation Kit Information

The ADP5090 is an ultralow, power synchronous, dc-to-dc boost regulator in a compact 3 mm × 3 mm LFCSP_WQ package. The ADP5090 runs from input voltages of 0.38 V to 3.3 V and requires minimal external components to provide a high efficiency solution with integrated power switch, synchronous rectifier, and battery management.

The ADP5090 evaluation board provides an easy way to evaluate the device. This user guide describes how to quickly set up the board and deliver up to 3.5 V maximum voltage to the SYS output using an external resistor divide. The internal switches turn on as long as the storage element voltage at BAT pin is above the externally programmed SETSD of 2.4 V. The PGOOD indicator toggles high when SYS ramps up to 3 V.

EVAL-ADP5090-2

View Detailed Evaluation Kit Information

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.

EVAL-WSN

View Detailed Evaluation Kit Information

The Wireless Sensor Network (WSN) demo platform is a flexible, modular system for evaluating all aspects of a WSN. It offers both an out-of-the-box demonstration system, and can also be used as a development platform. It contains all of the hardware and software necessary to implement a plug-and-play WSN. The hardware includes a base station node along with multiple sensor nodes that support many different sensors. The system is flexible in that sensors can be connected in any combination to any of the sensor nodes. The out-of-the-box utility of the WSN development kits significantly reduces the time and effort required to move a customer’s design from proof-of-concept phase to production release through the marriage of three Multi-Sensor Node Boards, a gateway connector, an emulator platform, and a full featured software package.
