Evaluation and Demonstration Boards and Kits have become a major resource for embedded-system and application developers. They offer a variety of ways for developers to investigate new technologies, evaluate components and test product designs. There are many different types of Evaluation and Demonstration Boards and Kits available today, such as the Texas Instruments TPS24740EVM-596. This article will explore the application field and working principle of the TPS24740EVM-596.

The TPS24740EVM-596 is a compact evaluation module for the TPS24740 synchronous buck regulator from Texas Instruments. The main application of the TPS24740 synchronous buck regulator is in power supply designs where the load current is more than 70mA . The TPS24740EVM-596 is used to evaluate the fundamental functionality of the device, such as load regulation, output ripple, power efficiency, and line transient response. It can also be used to evaluate the advanced features of the device, such as adjustable output voltage, soft start, adjustable switching frequency, external synchronization, and a power-good signal.

The TPS24740EVM-596 is equipped with an integrated inductor, output capacitor, and all the necessary discrete components to build a synchronous buck converter. The board is designed to provide easy access to the device’s output and control terminals. It also features additional test points with DUT mode selection, input voltage sensing, inductor current sensing, and output voltage sensing. These features make the TPS24740EVM-596 versatile enough for developers to evaluate different designs in different current ranges. The board also has an oscilloscope probe with a frequency filter, which can be used to measure the inductor current and output voltage ripple.

The TPS24740EVM-596 is powered by a 5V adapter and a 24V/3A power supply. The input voltage can also be varied from 24V to 36V. This allows developers to evaluate different voltage scenarios and optimize their design. The output voltage of the TPS24740EVM-596 can be adjusted from 0.8V to 3.3V. The output load current can be adjusted up to 700mA. The board can also be used to evaluate the performance of extreme low load currents.

The board also features two sets of status LEDs: one set indicates the regulator current limit, over-voltage protection, and power OK; the other set gives a visual indication of the current and output voltage. This helps the user to easily check the power supply performance. The board also has a number of features designed to reduce power dissipation and maximize thermal efficiency.

The TPS24740EVM-596 includes a graphical user interface GUI, which provides access to the complete set of features of the TPS24740 synchronous buck regulator. The GUI allows the user to adjust the operating parameters, such as switching frequency, output voltage, and current limit. It also includes plots and tables that can be used to monitor the operation of the TPS24740.

In summary, the TPS24740EVM-596 evaluation module is well-suited for evaluation and demonstration of a TPS24740 synchronous buck regulator. It provides access to a variety of features, such as load regulation, output ripple, power efficiency, and line transient response. More importantly, it offers a graphical user interface with plots and tables, which can be used to monitor the operation of the TPS24740 device. The board is equipped with test points, status LEDs, and power supplies, making it an ideal solution for developers to evaluate and optimize their power supply designs.
