These products deliver improved power density and efficiency, combined with excellent accuracy and low noise performance in a wide variety of applications, and the evaluation board helps users quickly and easily experience their performance in multiple use cases.

Overview of TPS7A6301EVM

The TPS7A6301EVM is composed of two parts, the main board and the control board. The main board provides two switching channels of input power supply, while the control board board provides the functions of adjusting the output voltage such as enabling steady state operation, monitoring the output voltage and measuring the output current. The power input ranges from 8V to 30V, and the output voltage can be adjusted from 0V to 12V. It also comes with on-board protection such as input current and thermal overload, reverse current and short circuit of the output voltage.

Operating Principle

The TPS7A6301EVM evaluation board is powered by a regulated 24V input voltage source. The 24V input voltage is then used to power the two switching channels of the main board. The two switching channels consists of input capacitance and inductance that works in tandem to produce a stable DC input voltage. This DC voltage is then fed to the control board and its used to allow the output voltage to be adjusted and monitored.

The TPS7A6301EVM operates in a constant voltage-damping mode. In this mode, the output voltage of the regulator is regulated through the damping mechanism, where the output voltage is kept constant by controlling the strength of the feedback applied to the output stages. The control board allows users to adjust the damping level by changing the feedback resistor in order to adjust the output voltage.

Features

The TPS7A6301EVM is a versatile board offering a few unique features. Firstly, it can monitor both input current and output voltage using a two channel Analog Multiplexer (MUX). This allows users to quickly observe and adjust the two parameters in real time.

The board also includes an on-board voltage reference that is used for calibration. It can be used to measure the input and output voltage and current accuracy. Furthermore, the TPS7A6301EVM includes two voltage dividers on the output that allows for safety testing in both normal and faulty condition.

Applications of TPS7A6301EVM

The TPS7A6301EVM is an ideal board for evaluating the performance of fixed high-voltage linear voltage regulators. It can be used for testing various parameters and features of the TPS7A6300 and TPS7A6301, including input current monitoring, voltage regulation, current accuracy, and safety testing.

The TPS7A6301EVM can be used in a wide variety of applications, such as industrial and home automation systems, consumer electronic devices, automotive electronics, telecom equipment, medical equipment, and more. It is also useful for evaluating the performance of possible future designs utilizing these products.

Conclusion

Texas Instruments’ TPS7A6301EVM is a highly versatile evaluation board designed for quickly and easily evaluating the performance of the TPS7A6300 and TPS7A6301 fixed high-voltage linear voltage regulators. It provides a wide range of features that make it ideal for testing a variety of parameters and features of the regulators, and it can be used in a wide variety of applications.
