Programmable Maximum Power Point Tracking Controller for Photovoltaic Solar Panels - SM72441

SM72441 (ACTIVE)

Programmable Maximum Power Point Tracking Controller for Photovoltaic Solar Panels

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.
