Product overview
Description
The STEVAL-ISV020V1 is an evaluation board based on the ultralow power energy harvester and battery charger SPV1050. For any detail related to the SPV1050 features and performances please refer to the datasheet.
The evaluation board implements the buck-boost configuration of the DC-DC converter and has the purpose of enhancing the SPV1050 based applications development by testing the silicon performance thanks to many jumpers and test points, and by helping to find out the best system configuration to make the SPV1050 device working at the most of efficiency.
The STEVAL-ISV020V1 board is optimized to:
Harvest energy from PV panels supplying 2.6 V ≤ VMP≤ 9 V and 10 μA ≤ IMP≤ 20 mA.
Charge a battery with the 3.7 V undervoltage protection threshold (VUVP) and 4.2 V end of charge voltage threshold (VEOC).
Nevertheless, few easy changes on the application components (input and output resistor partitioning, CINcapacitor) allow to use a different PV panel and source (like TEG), and battery, by setting the VMPP_SET, the VUVPand the VEOCthresholds according to the source and load. More in detail, operating ranges can be extended as follows: VMPfrom 150 mV up to 18 V, IMPup to 100 mA, VUVPdown to 2.2 V and VEOCup to 5.3 V.
