SM72442  
Programmable Maximum Power Point Tracking Controller  
for Photovoltaic Solar Panels  
General Description  
Features  
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 cir-  
cuit. Along with the SM72295 (Photovoltaic Full Bridge Driv-  
er), 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 configu-  
ration. Externally programmable values include maximum  
output voltage and current as well as different settings forslew  
rate, soft-start and Panel Mode.
