SM72445
Description
The SM72445 is a programmable MPPT controller capable of controlling four PWM gate drive signals for a 4-switch buck-boost converter. The SM72445 also features a proprietary algorithm called Panel Mode (PM) which allows for the panel to be connected directly to the output of the power optimizer circuit when the input to output voltage ratio is close to 1.
