Texas Instruments\' TPS65280EVM is an evaluation and demonstration board, which is mainly used for testing the working principle and performance of the TPS65280 low quiescent current buck-boost converter. This board enables users to easily and quickly evaluate the IC\'s performance, and accurately predict the specific application field.

The TPS65280 provides a solution for battery-powered, small size, portable, point-of-load step-down and boost converters with a small form factor that is easier to implement than traditional transformer-based designs. This device combines all the components needed for a DC/DC buck-boost converter onto one chip, thus reducing the design complexity and cost. The device also has a tiny package, allowing it to be used in areas that are traditionally notable for battery-powered and portable applications.

The TPS65280EVM is based on the TPS65280 IC and allows users to efficiently test and evaluate the design in a real-world environment. This board can be used to evaluate the performance of the TPS65280, as well as to explore and develop new application fields. It contains a Buck-BOOST+LDO design that uses TI\'s TPS65280 as the main DC/DC converter. The EVM is also equipped with a step-up converter, a low dropout (LDO) regulator, and a voltage supervisor. The TPS65280EVM also contains all other components needed to build a complete converter such as inductors, capacitors, and resistors.

In addition, it also provides easy-to-access items for making the necessary adjustments to the circuit and verifying the operation. For example, the TPS65280EVM provides a pair of variable output voltage (VADJ) pads, allowing users to adjust the output voltage quickly and easily. Also, the TPS65280EVM features an enable/disable switch for the LDO, as well as a jumper for the booster output voltage setting. The ENABLE/DISABLE switch on the board allows users to power on/off the voltage supervisor easily. Additionally, on-board jumpers are available for the buck-boost and low dropout (LDO) circuits.

The board also has an IC debug interface for programming and testing, which allows users to freely adjust the parameters of the converter. The TPS65280EVM has been designed to support TI\'s Easy-to-Use Evaluation Software (EUTES). This powerful software simplifies the testing process by providing a full graphical view of the circuit, live input and output voltage and current traces, and real-time performance monitoring. The software also allows users to save and compare test results, and to perform detailed modifications and parameter adjustments.

The TPS65280EVM application field and working principle are especially useful for battery-powered and portable applications, as it provides users with the ability to evaluate and test the performance of the TPS65280 IC in real-world environments. Furthermore, it is an excellent tool for developing new applications, as it provides an easy-to-use graphical evaluation software which simplifies the testing process and allows for precise parameter adjustments. As such, the TPS65280EVM is an ideal tool for evaluating and testing the performance of the TPS65280, as well as developing new application fields.
