The SM72442 is a programmable MPPT controller capable of controlling four PWM gate drive
signals for a 4-switch buck-boost converter. The SM72442 also features a proprietary algorithm
called Panel Mode which allows for the panel to be connected directly to the output of your power
optimizer circuit. Along with the SM72295 (Photovoltaic Full Bridge Driver), it creates a solution
for an MPPT configured DC-DC converter with efficiencies up to 99.5%. Integrated into the chip is
an 8-channel, 12 bit A/D converter used to sense input and output voltages and currents, as well as
board configuration. Externally programmable values include maximum output voltage and current as
well as different settings forslew rate, soft-start and Panel Mode.
