so after >>1843458 introduced me to the concept of MPPT, I've been trying to read up on it and figure out how to implement it with my shitty solar panel

the diagrams always show some kind of input to the buck (or boost) converter. What is the MPPT controller actually controlling on the buck converter?
I assume it's outputting a PWM signal to the base/gate of the buck switching transistor, which would vary the voltage and thus the load provided by the buck converter?
