Evaluation boards are commonly designed for use in evaluating large pieces of equipment like linear voltage regulators, and the Texas Instruments LP3878-ADJEVAL board is no exception to that. The LP3878-ADJEVAL board has been designed to evaluate and perform application oriented testing of the LP3878, a linear voltage regulator designed and manufactured by Texas Instruments. The LP3878-ADJEVAL board is designed to allow users to quickly and easily evaluate, test, and identify the correspondence voltage and temperature ranges of the LP3878 AC/DC linear regulator.

The LP3878-ADJEVAL board consists of two parts, the main board and a daughter board. The main board includes the LP3878 control loop, an adjustable output voltage, a microcontroller to run evaluation scripts, a power supply filter, high side and low side sense resistors, current flow indicators, and signal traces for evaluating input and output voltage, temperature, and current. The daughter board contains the power dissipation components, a thermal management system, and an environment temperature sensor. The main board and daughter board are connected via USB, allowing the evaluation of the LP3878 from a PC.

The main feature of the LP3878-ADJEVAL board is its adjustable output voltage. This allows the user to adjust the output voltage of the linear regulator to any desired value, which can range from 0V to 8V, depending on the version of the board. This feature allows users to quickly and accurately evaluate the performance of the regulator at varying output voltage levels, ensuring optimum performance and stability.

In addition to the adjustable output voltage, the LP3878-ADJEVAL board also allows users to evaluate and adjust the thermals of the regulator. It includes a temperature sensor that can be used to monitor the temperature of the regulator, and an internal thermal management system that can be used to actively regulate the temperature of the device to maintain the desired operating temperature range. This feature can increase the overall lifetime of the linear regulator, as it allows for the active control of the temperature of the device.

The LP3878-ADJEVAL board also includes an accompanying software package for evaluation and testing purposes. This software can provide users with comprehensive data about the performance of the regulator, including input voltage, output voltage, current, temperature, and other parameters. The software can also be used to adjust the output voltage of the linear regulator, allowing the user to customize the performance of the device to suit their specific application requirements.

In conclusion, the LP3878-ADJEVAL board is an extremely useful tool for evaluating, testing, and customizing the LP3878 AC/DC linear regulator. With the adjustable output voltage, thermals monitoring, and accompanying software, the user can quickly and accurately assess the performance of the device and customize the performance to suit their needs. The LP3878-ADJEVAL board is an essential piece of equipment for anyone looking to evaluate the LP3878 or other linear voltage regulators.
