The TPS65400EVM-678 is an evaluation board that makes it much easier to test and evaluate the performance of off-line switch mode power supplies. This board provides a comprehensive test platform for the evaluation of the TPS65400, which is a high efficiency 500kHz, 3A synchronous buck converter from Texas Instruments.

The TPS65400EVM-678 is designed to evaluate the features and performance of the TPS65400. The evaluation board includes over-voltage protection, over-current protection and current limit adjustments. This board also includes circuit breakers and an output adjust potentiometer to adjust the power supply output voltage.

The TPS65400 is a highly integrated switching regulator that combines a switching buck regulator and an output driver in a single device. It features a programmable switching frequency, a current-sense comparator, and an adjustable output soft-start. The device operates at efficiency levels up to 92%, and also supports power conditions from 5V to 42V.

The TPS65400EVM-678 can be used in applications such as AC/DC power sources, telecom power supplies, and energy efficient power supplies for consumer and industrial applications. It also offers a comprehensive list of features such as power droop compensation, frequency compensation, and improved start-up. The evaluation board also includes a graphical user interface (GUI) control panel to monitor and adjust power settings.

On-board power measurements such as input voltage, output voltage, ripple voltage, switching frequency, efficiency and power dissipation can be monitored using the GUI control panel. The board also features an analog output voltage adjustment from 0V to 10V, an over-voltage protection trip voltage adjustment up to 42V, and a powergood signal output.

The TPS65400EVM-678 evaluation board is an ideal test platform for evaluating the performance of the TPS65400. Its wide operating voltage range, integrated power stages, and comprehensive GUI support make it ideal for testing power solutions in AC/DC and DC/DC off-line applications.
