TPS40345EVM-353

TPS40345EVF-353 is an Evaluation Boards – DC/DC & AC/DC (off-line) SMPS board specially designed to evaluate TPS40345. This board is primarily constructed to test the performance of 3A/ 600V buck converter in low power offline power applications. The evaluation board is equipped with several features to provide a comprehensive off-line power solution. The board contains a flyback capacitor, external schottky diode, gate drive, output isolation network, external transformer winding, input/output filter, output voltage sense circuit, and a separate output voltage/current control circuit. The board also includes several additional components to provide enhanced performance.

The TPS40345EVM-353 board has several application fields, and it can be used in commercial, industrial, and residential applications. It is applicable in several applications, such as home appliances, consumer electronics, communication systems, server systems, and automotive components. This board is also used to evaluate the efficiency, power loss, and overall performance of the TPS40345 buck converter. The evaluation board is capable of supporting up to 3A output current, and it is suitable for low power applications.

The TPS40345EVM-353 board has a simplified two-stage power conversion architecture, which contains a primary side power stage and a secondary side power stage. The primary side power stage includes the power switch, an insulation transformer, and a current sense network. The secondary side power stage consists of a current sense resistor, a rectifier, and a capacitance filter. The flyback transformer on the primary side and the rectifier bridge on the secondary side provide the galvanic isolation between the drive source and the load.

The input voltage on the board is from 12V to 32V DC. The maximum current load of the board is 3A, whilst the maximum power load is 600W. The output of the board is adjustable, and the output voltage of the board ranges from 0.8V to 20V. The output current of the board is monitored by monitoring the voltage across the current sense resistor. The voltage feedback is compared with the voltage reference, and the adjustment is then made to the output voltage accordingly.

The output of the board is also protected by an overvoltage, overcurrent, overload, and short-circuit protection. The board is also equipped with several additional features such as a quiet-zone compensation, undervoltage lockout (UVLO) protection, and current share protection. The board is also provided with two separate outputs for the resistance and capacitance loads. The board also provides an additional separate output for the turn-on/off control.

The TPS40345EVM-353 is a flexible and versatile board, and it is a great way to evaluate the performance of the TPS40345 buck converter in low power applications. The board provides users with comprehensive power solutions that can be used for various applications in different fields. In conclusion, the TPS40345EVM-353 is a great solution for users who require an off-line power solution with enhanced performance.
