SNVS689H –OCTOBER 2010–REVISED APRIL 2013

Programmable Maximum Power Point Tracking Controller for Photovoltaic Solar Panels

Check for Samples: SM72442

FEATURES

DESCRIPTION

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.
