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.
