STEVAL-ISV020V1

Evaluation board based on the ultralow power energy harvester and battery charger SPV1050, 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 2.6V ≤ VMP ≤ 9V and 10 µA ≤ IMP ≤ 20mA. Charge a battery with the 3.7V undervoltage protection threshold (VUVP) and 4.2V end of charge voltage threshold (VEOC).

• First start-up at Vin is 2.6V
• Input voltage working range 150mV ≤ Vin ≤ 18V
• End of charge battery voltage VEOC is 4.25V
• Battery undervoltage protection VUVP is 3.7V
