The TPS543C20EVM-869 is an evaluation module for the TPS543C20 family of off-line switching controllers. It is designed to give a hands-on experience of the features and usage of the controllers in applications involving SMPS, which includes DC/DC and AC/DC (Off-Line) SMPS.

The TPS543C20 family of parts is designed to provide a simple, efficient, low-cost, and easily programmable SMPS controller IC solution for high-performance applications. It follows the standard SMPS topology and integrates the power element into the controller. It is optimized to support secondary-side post-regulators and pre-regulation along with primary-side post-regulation like hysteretic or closed loop control. It features multiple safety features such as short-circuit protection and temperature shutdown, VCC overvoltage protection, and output power-good indicator.

The TPS543C20EVM-869 board includes the TPS543C20 IC, gate driver, necessary MOSFETs, and other components. The TPS543C20EVM-869 can help engineers in easily evaluating the performance of the TPS543C20 and implementing their design quickly. The EVM also provides flexibility to the users by allowing them to explore different features like the functions available for input, output, and sense pins. Moreover, the EVM has all the necessary warning labels present on the board itself to make sure the users operate the EVM safely.

The TPS543C20EVM-869 is designed to work with isolated and non-isolated topologies. The board features a 12V/0.12A output which can be adjusted from 0-12V/0.12A. The EVM has four state-of-the-art controllers such as standard SMPS, auto-fault-protect, auto-compensation, and constant current mode, making it ideal for wide-range applications. The EVM has industry standard SMPS features like soft-start, over-current protection, and thermal shut down. It also features an adjustable switching frequency of 10kHz to 1MHz, which can be adjusted via the board’s trimmer potentiometer.

The TPS543C20EVM-869 has a very simple generic application circuit for single-phase buck converter. The comprehensive evaluation software offered facilitates the user to communicate with the controller IC via a USB interface and change the different parameters implemented in the EVM, like switching frequency, output voltage, and current limit. This helps in optimally tuning the operating conditions of the IC. The software provides easy access to diverse settings, other than offering data logging feature.

In summary, The TPS543C20EVM-869 is an excellent choice for design engineers who need to evaluate the features and performance of the TPS543C20 IC for applications involving DC/DC and AC/DC (Off-Line) SMPS. It is designed to facilitate easy evaluation as well as implementation of the controller’s functions and features. It supports multiple safety features and additional flexibility is provided by the evaluation software that allows complete control over the IC.
