The SM72445MTE/NOPB from Texas Instruments is a programmable Maximum Power Point Tracking (MPPT) controller. It is designed to control four PWM gate drive signals for a 4-switch buck-boost converter, making it suitable for photovoltaic solar panel applications.
This controller operates with an input voltage range of 4.75V to 5.25V and has an operating temperature range of -40°C to 105°C. It features adjustable PWM frequencies of 110kHz, 135kHz, or 215kHz. The device includes a proprietary Panel Mode (PM) algorithm that allows direct connection of the panel to the output of the power optimizer circuit when the input-to-output voltage ratio is close to 1, optimizing efficiency.
Key features include photovoltaic solar panel voltage and current diagnostics, an I2C interface for communication, output overvoltage protection, and over-current protection. The SM72445MTE/NOPB is housed in a 28-TSSOP package and is designed for surface mount applications. It also integrates an 8-channel, 10-bit A/D converter for sensing input and output voltages and currents.
