STEVAL-ISV015V1, Demonstration Board based on the SPV1040 and LD39050, Up to 2.5-W solar USB supply

STEVAL-ISV015V1, Demonstration Board based on the SPV1040 and LD39050, Up to 2.5-W solar USB supply. The STEVAL-ISV015V1 demonstration board is a solar harvester system designed to supply USB devices and is based on the ST devices SPV1040 (solar voltage boost converter) and LD39050 (voltage regulator with low quiescent current and low noise). The SPV1040 is a high efficiency, low power and low voltage monolithic step-up converter that operates over a 0.3 V to 5 V input voltage range, therefore allowing the use of even a few solar cells in all portable applications where the capability of handling low input voltages is of utmost importance. Despite the variation of several conditions throughout the day (such as irradiation, dirt, temperature, etc.)
