@Semiman_#1: True. If you wanted to achieve temperature-invariant MPPT with this chip, it looks like you'd have to detach Vs and CSN from INTVCC, and re-attach the pins to an external temperature-sensing diode. You'd need to tweak the resistor values accordingly. I haven't shopped around, but it would seem reasonable for solar panel makers to include a temperature-sensing diode in the center of the panel; the panel's MPPT should track the diode's open-circuit voltage fairly well. If that's not the case, then you can always glue a diode to the panel and drive it with a current source (resistor to INTVCC).
It's a somewhat simplistic view of maximum power point tracking and would apply to one panel, at one temperature. It would not achieve anywhere near 100% utilization in the real world as the maximum power point voltage will vary considerably with temperature ... which is impacted by solar irradiance as well.
This chip has multiple features tied together and designers of UPS,inverters also can benefit. If this chip could be combined with a digital technology with a simple user interface to program various parameters of currents and voltages then it will be more easy to incorporate into many systems.
