TPS4H000EVM

Evaluation and Demonstration Boards and Kits are essential tools for designers and engineers wanting to prototype, evaluate, and test new products quickly. The TPS4H000EVM evaluation board and kit is designed to demonstrate the capabilities of TI’s TPS4H000, a highly efficient, compact single-channel Power Management IC. The board offers a wide range of features and options, providing users with an easy and reliable way to develop their designs.

The TPS4H000EVM board uses a Texas Instruments TPS40400 high voltage step-down converter with integrated buck, boost, and linear regulators. It is capable of converting an input voltage up to 15V down to 0.9V. The board has an adjustable output voltage and up to 20A continuous output current capability. It features PMOS and LDO controllers which allow for a low-noise, low-ripple output. The board supports various protection features like thermal shutdown, short-circuit protection, output over-voltage protection, and over-current protection.

The TPS4H000EVM also features a complete range of peripheral components and connectors including LED indicators, USB connectors, JTAG headers and voltage measurement points. The board offers a low dropout voltage of 0.1V while also providing over-temperature and over-current shutdown protection. The output voltage accuracy, load regulation, noise level, and other parameters of the board can be adjusted through on-board trimpots. The board also provides an adjustable UVLO (Under-Voltage Lockout).

The TPS4H000EVM can be used for a wide variety of applications including power management and control for telecom, consumer, and automotive applications. It can also be employed in industrial, medical, and measurement and testing equipment where very low noise and high efficiency is required. The board can be used for point-of-load (POL) design as well as pre-regulation designs and is ideal for a wide range of applications requiring high efficiency and power density. With its flexible design, the TPS4H000EVM can be used in applications requiring a high degree of portability.

The TPS4H000EVM’s working principle is based on using the TPS4H000’s PWM controller to generate the reset signal for the buck regulator, the linear regulator, and the boost regulator. The PWM controller senses the input voltage and the detected voltage is then converted to a reference voltage which is used by both the buck and boost regulators. The controllable output voltage range of the buck and boost regulators are dynamically determined by the reference voltage.

The TPS4H000EVM board is a complete evaluation and development solution for designers and engineers who are looking to rapidly prototype, evaluate, and test power management designs. It is designed with a simple and intuitive user interface, allowing the board to be used for a wide variety of applications by applying the appropriate settings. The board provides on-board voltage and current measurement which allows users to accurately monitor and test their designs. Combined with its flexibility, ease-of-use, and high efficiency, the TPS4H000EVM board is an ideal choice for power management applications.
