Description
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, capable of maximizing
the energy generated by 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 1.8 A) is reached or the
maximum temperature limit (up to 155 °C) is
exceeded. An additional built-in feature of the
SPV1040 is the input source reverse polarity
protection, which prevents damage in case of
reverse connection of the solar panel on the
input.
