7.3.1 TI Fusion GUI

The Texas Instruments Fusion Digital Power Designer is provided for device configuration. This PC-based graphical user interface (GUI) offers an intuitive I2C/PMBus interface to the device. It allows the design engineer to configure the system operating parameters for the application without directly using PMBus commands, store the configuration to on-chip nonvolatile memory, and observe system status (voltage, etc). Fusion Digital Power Designer is referenced throughout the data sheet as Fusion GUI and many sections include screenshots. The Fusion GUI can be downloaded from www.ti.com.
