SM72445MT/NOPB Description

The SM72445MT/NOPB is a programmable MPPT controller capable of controlling four PWM gate drive signals for a 4-switch buck-boost converter. The SM72445MT/NOPB 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. This provides an opportunity to optimize the efficiency of the power optimizer when the load is naturally matching the maximum power point of the panel.
