The SM72445MT/NOPB is a programmable Maximum Power Point Tracking (MPPT) controller designed for renewable energy applications, specifically for photovoltaic systems. It operates with adjustable PWM frequencies of 110kHz, 135kHz, or 215kHz and is capable of controlling four PWM gate drive signals for a 4-switch buck-boost converter. The device features a proprietary Panel Mode algorithm that optimizes efficiency when the load matches the maximum power point of the solar panel. This controller includes an integrated 8-channel, 10-bit A/D converter for monitoring input and output voltages and currents, as well as IC configuration settings. It supports I2C communication for configuration and control, and offers built-in protections such as output overvoltage and over-current protection. The SM72445 is packaged in a TSSOP-28 format and operates within a temperature range of -40¬8C to 125¬8C, making it suitable for various environmental conditions.
