Selecting SPV1040 for energy harvesting from solar cell

[JFran.18]

Hi,

This is John from Qmax Systems, 

We are designing a product - energy harvesting from solar cell. Our application requires a boost converter to convert 0.5V to 4.2V with an output current of min 100 mA. Do you think LTC3105 will support this application? If not, can you please suggest any other device for this application?

Regards

Hi John,

Did you succeed in resolving your issue? I am trying to make SPV1040 work with a solar cell that is able to provide 0.6 V (Voc) and 100 mA (Isc), but the voltage output is never stepped up using this low input voltage. The datasheet states that the converter can work with an input voltage as low as 0.3 V. I have tried even connecting directly a power supply as if it was the solar panel, and the output voltage only steps up with input voltages greater than 0.85 V. Any help coming from your experience would be highly appreciated!

Kind regards.
