DC DC Converters

DC-DC converters are electronic electrical components used for converting a DC voltage at one level to another. They are used in applications ranging from consumer electronics, automobiles and aviation, to telecommunications and industrial systems. The CXE15-48S2V5 is an example of a DC-DC converter, and understanding its application field and working principle can help designers make better decisions when selecting these components.

Application Field

The CXE15-48S2V5 is a DC-DC converter used for providing stably regulated DC voltage for industrial and consumer electronics devices. It can convert DC power effectively when needed and provide high efficiency to allow for longer battery life in portable electronic devices such as notebooks, camcorders, tablets, and mobile phones. This converter is designed to support a wide range of input voltages, from 3V – 48V, while still providing a regulated output of 5V, with an efficiency as high as 96%.

This converter is capable of delivering 15W of power and is designed to operate in temperatures ranging from -40°C to 70°C, making it a suitable choice for applications in extended temperatures such as car/truck/drone environments.

Working Principle

The CXE15-48S2V5 works by using an internal power switch to turn on and off an inductor rapidly. As the switch turns on, an electrical current flows through the inductor, storing energy in the magnetic field. When the switch turns off, the inductor’s energy is released in a regulated output voltage. This flow of energy has been compared to a water wheel: as the current alternates on and off, the energy is transferred from the inductor to the load. The load can be any device needing additional power, such as a mobile phone, tablet, car power system, etc.

Protection Features

The CXE15-48S2V5 also provides several protective features. It has an over temperature protection that activates after reaching 80°C, as well as over voltage and short-circuit protection that shuts down the circuit and protect the device from being damaged. This converter also includes a Current Mode Control that monitors the output current and shuts down the converter if something goes wrong.

Conclusion

The CXE15-48S2V5 DC-DC converter provides an efficient and cost-effective way to regulate power and provide a stable output in portable electronic and industrial applications. By understanding its application field and working principle, designers can make better decisions when selecting a DC-DC converter.
