Programmable Maximum Power Point Tracking Controller
for Photovoltaic Solar Panels
General Description
The SM72441 is a programmable MPPT controller capable of
controlling four PWM gate drive signals for a 4-switch buck-
boost converter. Along with SM72295 (Photovoltaic Full
Bridge Driver) it creates a solution for an MPPT configured
DC-DC converter with efficiencies up to 98.5%. Integrated in-
to the chip is an 8-channel, 12 bit A/D converter used to sense
input and output voltage and current, as well as board con-
figuration. Externally programmable values include maximum
output voltage and current as well as different settings on slew
rate, and soft-start.
