www.ti.com SNOSB64G – OCTOBER 2010 – REVISED APRIL 2013 SM72441 Programmable Maximum Power Point Tracking Controller for Photovoltaic Solar
Panels
Check for Samples: SM72441 FEATURES 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 into the chip is an
8-channel, 12 bit A/D converter used to sense input
and output voltage and current, as well as board
configuration. Externally programmable values
include maximum output voltage and current as well
as different settings on slew rate, and soft-start. 1 2 Renewable Energy Grade
