TPS65276EVM evaluation board is a comprehensive tool for designing, testing, and optimizing DC/DC & AC/DC (Off-Line) SMPS applications. The board enables the evaluation of a 1.2 A TPS65276EVM buck regulator integrated circuit (IC) combined with its associated external components. A wide input source range from 5 V to 24 V enables use of the design in a broad set of applications. The output can be easily programmed to provide an adjustable voltage range from 0.8 V to 5 V. The board also contains a second buck regulator and a linear regulator enabling different combinations of regulators to be evaluated. Software support can also be provided for simulation, BOM estimation, and design template generation.

The TPS65276EVM is composed of two main components: the TPS65276EVM integrated circuit (IC) and the TPS65276EVM Evaluation Board. The Evaluation Board utilizes the TPS65276EVM buck regulator IC to provide voltage conversion from the input DC supply to the desired adjustable output voltage. The board also includes a linear regulator to enable the simultaneous operation of two independent voltage outputs. The use of two buck regulators as the main switching regulators on the TPS65276EVM board avoids the requirement for a signal transformer and separates the input power supply noise from the switching noise.

TPS65276EVM board is composed of the following components: a TPS65276EVM buck regulator IC, two primary switches, several Schurter Group EMC-certified converters, two linear regulators, three optional isolators, and three optional waveshaping networks. The primary switches are used as the main rate-dependent switches in the TPS65276EVM buck regulator. The other components are used to filter the ripple noise at the output by shaping the waveform of dV/dt, Vd/dt, and the output voltage. The Schurter switching converters allow for safe power sequencing and provide excellent EMC performance. The linear regulators are used to adjust the output voltage of the TPS65276EVM buck regulator to the desired values.

To begin the process of evaluating the TPS65276EVM board, the user should connect the board to the output of the desired power source and set the external components according to the application. The TPS65276EVM IC should then be configured according to the needs of the application and the user should determine the required output voltage. The board will then convert the input voltage to the specified output voltage. The output noise can be reduced using the provided theschurter EMC-certified converters. The user should also ensure that the two linear regulators are configured properly for the desired output.

The TPS65276EVM board can be evaluated using a scope or other measurement equipment to analyze the signals. The board also supports simulation with PowerFont (supplied software) for evaluation of the design methodology. The BOM estimation tool provides an estimation of the materials and components required for the design and the design template function simplifies the evaluation procedure by providing an easy-to-follow template to complete the evaluation.

In conclusion, the TPS65276EVM evaluation board provides a precise and efficient tool to evaluate DC/DC & AC/DC (Off-Line) SMPS applications. The board is composed of the TPS65276EVM buck regulator IC, two primary switches, several Schurter Group EMC-certified converters, two linear regulators, three optional isolators, and three optional waveshaping networks. The board also supports simulation with PowerFont (supplied software) and provides a BOM estimation tool and a design template function for easy evaluation.
