Hello. I am using the SPV1040 solar boost converter within the STEVAL-ISV012V1 development board. The datasheet states that the converter can work with an input voltage as low as 0.3 V. The solar cell I am using 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.
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. Should I change any component in the design to achieve boosting from inputs as low as 0.3 V, as stated in the specifications?
Any help would be highly appreciated!
