This application report shows the benefits of using a step-down converter with an I2C communication interface. Several applications benefit from controlling features and reading status information from a power management device. TI offers step-down converters with an I2C communication interface, which focus on design flexibility while keeping a small solution size.

When it comes to power management, many systems benefit from step-down converters with already built-in features. However, adding more features requires more pins to implement them. Offering more features can be at odds with the need to increase the power density. To achieve both, some buck converters use an I2C interface, which enables digital communication to control such features, read status information or adjust the buck converter control modes depending on the system operating conditions .
