The TPS43351EVM is an evaluation module (EVM) designed to facilitate customers in the testing, prototyping, and evaluation of Texas Instrument\'s TPS43351 and TPS43353 synchronous buck controllers. The TPS43351EVM is an offline, switch mode power supply (SMPS) that uses a DC/DC or AC/DC topology. The module offers a fixed 8V output voltage, adjustable output voltage, adjustable output current limit, and adjustable switching frequency.

The TPS43351EVM consists of a high-performance TPS43351 synchronous buck controller, power-switching output MOSFETs, integrated input/output bypass capacitors, and a set of supporting circuitry. The module operates from either a DC or AC input voltage and provides a constant voltage output. The TPS43351EVM can generate output voltages ranging from 0.6V to 8V with the help of intuitive user interface. The module supports current-mode control and cycle-by-cycle current-limit protection.

The TPS43351EVM provides internal compensation for use with external sense compensation. Additionally, the module supports adjustable soft-start times and current-limit thresholds. The TPS43351EVM features an adjustable switching frequency between 200kHz and 1.1MHz, allowing the user to select the optimal switching frequency for their application. It also provides integrated output overvoltage and undervoltage protection, as well as a power good function to signal output voltage correctness. The TPS43351EVM also features a configurable enabling/shutdown functionality for remote system power control.

The TPS43351EVM provides a robust platform to evaluate the features and performance of the TPS43351 and TPS43353 synchronous buck controllers. The module is suitable for a wide range of offline, isolated and non-isolated applications, such as AC/DC wall adapters and battery chargers. The module is also suitable for automotive applications, where its current-mode control and adjustable switching frequency allows it to achieve minimal noise and power losses. From a design standpoint, the TPS43351EVM simplifies the design and development process by providing a single, integrated solution for testing, prototyping, and evaluation.
