Solar cell maximum power point tracking (MPPT) is to ensure that the photovoltaic cell always outputs maximum power when the light intensity changes to make full use of solar energy. In general, it is necessary to implement the MPPT function with a switch e DC-DC converter to maximize the product of the output voltage and the charging current (output power).
CN3722 adopts switching buck e DC-DC conversion to realize the maximum power point tracking function of photovoltaic cells. Its input voltage can reach up to 28V, which is very suitable for applications where the input voltage and battery voltage are relatively different.
