It enables 1-port solutions delivering up to 15W and 2-port solutions delivering up to 10W.

The TPS2371PWR enables portable applications to reduce solution size, eliminate the need for extra EMI filters, and meet safety requirements using just one controller. It is optimized for USB Type-C designs and provides the highest integration by combining a QFN package with an included external inductor. The dual-channel design allows for a wide range for input voltages, making it suitable for many applications.

Application Field

The TPS2371PWR is suitable for a broad range of applications such as smart phones, tablets, portable media players, notebook PCs, network ICs, and other portable electronic devices. The controller offers a variety of features to help designers reduce system cost, save size, and provide a robust power delivery solution for their designs. The scalability of the TPS2371PWR makes it a good fit for other applications such as industrial and medical.

Design Freedom

The TPS2371PWR provides a high degree of design freedom due to its integrated acoustic filter, integrated overvoltage protection, adjustable current limit, and internal soft-start. This design flexibility allows designers to create a solution that optimally meets their goals in terms of cost and performance. Additionally, the controller is able to accommodate a wide input voltage range, which is suitable for applications that require two or more independent voltage rails.

Working Principle

The basic working principle of the TPS2371PWR is to convert a high input voltage into a regulated low-voltage output. This controller contains a comparator, amplifier, and MOSFET switching circuit to facilitate the conversion. The controller monitors the output voltage and adjusts the switching cycle to regulate the output. The TPS2371PWR also utilizes a voltage-mode control algorithm with feed-forward compensation, allowing for quick loop response times and improved noise immunity.

The controller also has integrated overvoltage protection and acoustic noise filters for improved system performance. The overvoltage protection ensures that the output voltage does not exceed the limit, while the integrated acoustic filter ensures that the component meets the EMI requirements. Additionally, the controller has an adjustable current limit which can be used to protect the system components from over-current and allow the system to operate at safe levels.

Conclusion

The TPS2371PWR is a very versatile and reliable 1.5cm I/O regulator that can be used in a variety of applications. It provides a high level of integration and a wide input voltage range with integrated overvoltage protection, FM acoustic noise filter, and adjustable current limit. This makes the TPS2371PWR an attractive solution for many applications, particularly those that require a small, efficient, and low-cost power delivery solution.
