Introduction
NCP345EVB is a evaluation and demonstration board and kit that provides a low-noise power solution for automotive applications, enabling designers to quickly and easily evaluate performance. The field of application and working principle of NCP345EVB will be discussed in this paper.

Application Field
NCP345EVB is designed to be used in automotive applications such as engine control units (ECUs), heads-up display (HUD) systems, and event data recorders (EDRs). It is also suitable for other automotive applications such as electric vehicle (EV) charging points, car battery monitoring, digital instrumentation clusters, multimedia infotainment systems, and in-car health monitoring systems. Furthermore, NCP345EVB can be used in smart home appliances, IoT devices, broadcast equipment, and medical applications.

Working Principle
NCP345EVB can provide a low-noise power solution even in a noisy environment. It is built around two buck regulators and one buck-boost regulator, with an adjustable voltage output option. The voltages are driven by two P-Ch MOSFETs and two N-Ch power MOSFETs, providing an output power range of 3.3V to 22V and a maximum output load of 7A. The switching frequency of the buck and buck-boost regulators can be adjusted from 1.2MHz to 5.5MHz, allowing users to optimize the component size and overall efficiency. Furthermore, NCP345EVB also has built-in protection features such as over current, over voltage, and thermal protection to ensure the board operates reliably and safely, even in extreme temperatures.

Conclusion
NCP345EVB is an evaluation and demonstration board and kit for automotive applications that provides a low-noise power solution even in a noisy environment. Its field of application is broad, ranging from automotive to smart home appliances, IoT devices, broadcast equipment, and medical applications. In addition, NCP345EVB also features adjustable voltage output, adjustable switching frequency, and built-in protection features. This evaluation and demonstration board and kit can help designers quickly and easily evaluate the performance of their designs.
