Up to 5 W Solar Battery Charger with Embedded MPPT Based on SPV1040

COO (Country of Origin):
IT
The STEVAL-ISV006V2 demonstration board is
based on the SPV1040 high efficiency solar
battery charger with embedded MPPT. The
SPV1040 device is a low power, low voltage,
monolithic step-up converter with an input voltage
range from 0.3 V to 5.5 V, and is capable of
maximizing the energy generated by even a single
solar cell (or fuel cell), where low input voltage
handling capability is extremely important.
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.
The device employs an input voltage regulation
loop, which fixes the charging battery voltage via
a resistor divider. The maximum output current is
set with a current sense resistor according to
charging current requirements.
The SPV1040 protects itself and other application
devices by stopping the PWM switching if either
the maximum current threshold (up to 2 A) is
reached or the maximum temperature limit (up to
155 °C) is exceeded.
