Power management and energy conversion techniques are essential to the growth of today’s technology, from consumer applications to high-performance industrial systems. As the demand for efficiency and performance continues to increase, so does the complexity of the components, circuits, and systems used to address them. When it comes to the challenge of efficiently managing the power and energy needs of systems in applications as diverse as telecom, industrial, medical, automotive, and consumer electronics, an essential tool that is required is the ability to evaluate the performance of different power-conversion components and their integration into the overall system. Texas Instruments, a leader in the field of analog integrated circuits, offers the TPS43000EVM, a complete power-conversion device evaluation platform for evaluating the performance of the TPS43000 integrated power-supply controller. This article will provide an overview of the TPS43000EVM and its application field and working principles.

The TPS43000EVM evaluates the performance of TI’s TPS43000 IC, which is an integrated power-supply controller for switch-mode power supplies such as DC-DC buck and boost converters. This controller supports up to three output channels, each of which can be independently adjusted for voltage and current. The TPS43000EVM allows users to modify the power-conversion architecture by changing the topology of the buck and boost stages, as well as setting the voltage and current for each output. The board can also be used to evaluate the performance of the TPS43000 IC in different operating conditions, such as low- and high-frequency switching, and in continuous-conduction-mode or critical mode. The TPS43000EVM also includes many features to simplify the characterization process, such as pre-programmed output commands, on-board software control and monitoring, and output discharge circuitry that allows for fast and easy test setup.

The TPS43000EVM is capable of supporting many different power-conversion designs, including buck topologies with single-ended or differential inputs, boost topologies with single-ended or differential output, DC-DC converters in continuous current-mode or critical-conduction-mode, and AC-DC converters in continuous-conduction-mode or critical-conduction-mode. It supports both single and multiple-output distributions as well as dual-core configurations. The TPS43000EVM also includes components to reduce noise and inductive ringing, as well as integrated protection features such as over-voltage-protection and over-current-protection. This provides a highly flexible platform for evaluating an expansive range of power-conversion topologies and architectures.

The TPS43000EVM is composed of a set of components which work together to provide a complete power-conversion evaluation platform. The IC itself is an integrated power-supply controller for switch-mode power supplies such as DC-DC buck and boost converters. It includes a dedicated inductance-setting circuit that allows for the independent adjustment of each output voltage. The board also includes a range of other components, including power MOSFETs, BJTs, zener diodes, MOSFET drivers, bootstraps, and resonant elements. The TPS43000EVM also includes peripheral components such as an LCD display, a rotary switch, and a set of LEDs for monitoring the status of the device. The board can be powered from both AC and DC sources, and includes a power source selection jumper to ensure the correct connection is made.

The TPS43000EVM uses a set of software control structures to provide a user-friendly interface for controlling the operation of the power-conversion device. This includes a GUI interface for programming and monitoring the operation of the TPS43000, as well as a set of macros for controlling the configuration and operation of the componentry on the board. The TPS43000EVM also includes a set of pre-programmed output commands that can be used to set the voltage and current of each output. This allows for fast and easy test setup and simplifies the development and characterization process.

The TPS43000EVM is a highly effective and versatile power-conversion evaluation platform for evaluating and characterizing a wide range of topologies and architectures. It is designed to simplify the design and characterization process, while providing a reliable and flexible platform for evaluating the performance of the TPS43000 integrated power-supply controller. The wide range of features, components, and software control structures provided on the board make it an ideal choice for engineers looking to quickly and accurately evaluate their power-conversion designs. With its wide range of support for different types of power-conversion architectures, the TPS43000EVM provides a comprehensive testing platform for the TPS43000 IC.
