The TPS7A4501EVM-385 is a linear voltage regulator from Texas Instruments designed for evaluation and ready-to-use. It is designed for use in applications ranging from low-voltage, adjustable voltage, or low-dropout (LDO) regulators. This particular evaluation board integrates the TPS7A4500 step-down voltage regulator, which supports an input voltage of up to 45 V with a minimum drop-out voltage of 1V. Such voltage regulation is needed in a variety of battery-powered applications such as IoT devices, telecom infrastructure for cellular networks, consumer electronics, automotive applications, and medical devices. This evaluation board is well-suited for a variety of applications in need of efficient, low-voltage linear voltage regulation.
The TPS7A4500 step-down voltage regulator integrated in this evaluation board is designed to work in a synchronous rectification mode, from any input voltage from 4.2 V to 45 V. By using a built-in synchronous rectifier, the regulator reduces power loss and increases efficiency. The operating frequency of this device can be set to 150 kHz or 2.2 MHz (default), which allows flexibility in designing portable applications. Furthermore, the TPS7A4500 step-down voltage regulator integrated in this evaluation board supports up to 3.25 A current capability, making it suitable for applications requiring a high-current load.
The TPS7A4500 step-down voltage regulator also includes features like short-circuit protection, thermal shutdown, input under-voltage lockout, and short current limit. These protection mechanisms protect the regulator and the system from steady-state and transient conditions, by limiting voltage overshoot and current above a certain threshold. The evaluation board also includes a number of features, such as the ability to set over-current shutoff threshold, pulse-skipping voltage converters, and adaptive current limit, amongst others. All these features are designed to provide robust protection and safe operation of the evaluation board. Additionally, the evaluation board includes protection diodes, ESD protection, and transient protection.
In addition to the features mentioned above, the TPS7A4500 step-down voltage regulator integrated in this evaluation board also provides a wide range of voltage options. This is done by interfacing it with a suitable switching regulator or DC-DC converter, allowing for an adjustable output voltage asrequired. Depending on the connected switching regulator/DC-DC converter, the output voltage can be set to any value within the operating voltage range of 4.2 V to 45 V, up to a current limit of 3.25 A.The following equation summarizes the working principle of the TPS7A4501EVM-385 evaluation board:Vout = Vin - (R1 x (R2/R1 + 1)) x ILoadwhere Vin is the input voltage, R1 and R2 are the output resistance, and Iload is the load current.
Overall, the TPS7A4501EVM-385 evaluation board is an ideal solution for applications in need of efficient, low-voltage linear voltage regulation. With its wide range of features and protection mechanisms, the evaluation board makes it easier to design and evaluate various types of applications that require low-voltage, adjustable voltage, or even LDO regulators.
