The STEVAL-ISV015V1 is a demonstration board mounting the SPV1040 device (solar energy harvester) as input stage and the LD39050PUR device (low noise and low quiescent current voltage regulator) as output stage. It targets any portable application powered by USB supply and merges the capability of the SPV1040 device to maximize the power extraction from solar modules with the high precision voltage regulation of the LD39050 device.
