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.
