The URB1D DC/DC converters from Mornsun offer a 40-160VDC ultra-wide input voltage and a (reinforced) insulation of 2250VDC. With the EN60950/EN50155 approvals they are all suitable for 72V, 96V and 110V railway vehicle electronic equipment such as railway monitoring equipment, air conditioner controller and information displays, etc.
The Saturn400 Energy Harvester from Sol Chip is a chip sized cost-effective, solar battery technology integrating solar energy sources with low power electronic devices. This unique Photo Voltaic (PV) cell produces six selectable voltages from 0.75V to 9V, each selectable voltage delivers a different current. In full daylight the maximum power that can be extracted is about 4.0mW, while in office lighting the power extracted is up to 22uW depending on ambient lighting intensity. Additional voltage levels and also several voltage and power levels can be delivered simultaneously from separate pins of the device.

Evaluation boards for easy development
For easy development Sol Chip provides the Sol Chip™ EVAL-101 evaluation board. The board allows a simple configuration of the Sol Chip Energy Harvester, and comes with a pre-soldered on board Sol Chip Saturn Photovoltaic chip and additional soldering pads. This EVAL-101 is available in three versions: 3V, 4,5V and a selectable output.

The EH01 from SiliconReef is a complete power management solution for a variety of energy-harvesting applications, providing a small and simple solution combining power from different sources: a DC wall adapter, photovoltaic cells and a Li-Ion battery.

This device enables a simple implementation of a 5V supply, like a USB charger compatible with the ITU standard for the Universal Charging Solution (L.1000). Using a high efficiency DC/DC converter the EH01 converts the voltage from the panel to a stable 5V output. In addition a Li-Ion Battery Charger (with numerous protection features) stores the excess energy from the panel in an external battery. This battery then complements the energy to the DC/DC converter when needed.

The EH01 also provides an interface for battery status monitoring. This can be done via a simple button making a LED pulse or via a microcontroller based serial communication

To help you designing your
EH01 application SiliconReef provides 3 different evaluation kits.
