- STEVAL-ISV006V2: solar battery charger using the SPV1040 AN3319
- STEVAL-ISV006V2 has been designed to recharge any type of battery (except lithium
- compound) which maximum voltage (VBATT_max) ≤ 5.2 V and supplied by up to 5 W PV
- panels (constrained by VOC<VBATT_max).
-
- 0.3 V to 5.5 V operating input voltage
- 140 mΩ internal synchronous rectifier
- 120 mΩ internal power active switch
- 100 kHz fixed PWM frequency
- Duty cycle controlled by MPPT algorithm
- Output voltage regulation, overcurrent and overtemperature protection
- Input source reverse polarity protection
- Built-in soft-start
- Up to 95% efficiency
- 3 mm x 4.4 mm TSSOP8 package
- Thanks to the embedded MPPT algorithm, even under varying environmental conditions (such as irradiation, dirt, temperature)
- the SPV1040 offers maximum efficiency in terms of power harvested from the cells and transferred to the output.
