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
