    ... Programmable Maximum Power Point Tracking Controller for Photovoltaic Solar Panels General Description The SM72441 is a programmable MPPT controller capable of controlling four PWM gate drive signals for a 4-switch buck- boost converter. Along with SM72295 (Photovoltaic Full Bridge Driver) it creates a solution for an MPPT configured DC-DC converter with efficiencies ...

    ... Figure 2 Typical Ap- AVIN PIN AVIN pin is an A/D input to sense the input voltage of SM72441. A resistor divider can be used to scale the max voltage to about 4V, which is 80% of the full scale of the A/D input. CONFIGURABLE SETTINGS The voltage on A0 sets the max output voltage; whereas the ...
