The Texas Instruments LM5056EVM evaluation module (EVM) provides the design engineer with a telemetry measurement IC board with a PMBus™ compliant SMBus/I2C interface. This application note describes the various functions of the board, how to test and evaluate it, and how to use the companion System Protection and Management graphical user interface (GUI). The GUI is used to collect telemetry, configure warning and fault thresholds, and assist the designer with selection of external components for a specific application. Use of the advanced telemetry and monitoring capabilities of this device requires the installation of the Texas Instruments System Protection and Management (SPM) graphical user interface.
