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 A  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, CIN capacitor) allow to use a different

PV panel and source (like TEG), and battery, by

setting the VMPP_SET, the VUVP and the VEOC

thresholds according to the source and load.

More in detail, operating ranges can be extended

as follows: VMP from 150 mV up to 18 V, IMP up to

100 mA, VUVP down to 2.2 V and VEOC up to

5.3 V
