DC-DC Converters: VI-25W-EW Application Field and Working Principle

DC-DC converters are devices that are used to convert electrical energy from one form to another. By transferring electrical energy from one form to another, DC-DC converters are used in a variety of applications, such as providing power for medical devices and household appliances, regulating voltage in communication systems as well as providing efficient power solutions for motor vehicles and portable electronics. One of the most popular DC-DC converters is the VI-25W-EW series. This article will discuss the application field and working principle of this DC-DC converter.VI-25W-EW is a high-efficiency DC-DC converter from Lite-On Power Solutions. This series is designed for applications that require up to 25 watts of total output power. The input voltage ranges between 9V to 36V and can be adjusted to provide a regulated output voltage of 5V or 12V. It is designed with a wide range of industry standard features, such as wide input range, low noise, high efficiency, and over-voltage protection. The applications of VI-25W-EW include industrial, medical, automotive, and communication equipment. This series can also be applied in battery applications, such as mobile phones, tablet PCs, and other portable electronic devices. This series is also applied in numerous applications related to communication systems, such as modems, Cisco routers, and gateways. The VI-25W-EW series is an ideal solution for applications that require high efficiency and low electromagnetic interference (EMI).The working principle of the VI-25W-EW series DC-DC converters is a switch-mode control scheme. This control scheme is based on the concept of switching the input voltage faster than the load can respond. When the switch is ON, the output voltage is maintained until the load current reaches a predetermined value. The output voltage then drops and the cycle repeats. The main components of the VI-25W-EW series are the input voltage sensing circuit, the switch, the control circuit, the feedback circuit, the filter inductor, the output capacitor, the output diode as well as the sense resistor. The input voltage sensing circuit is used to monitor the input voltage and provide accurate feedback to the control circuit. It is then up to the control circuit to adjust the switching interval overlaps accordingly. The switch is responsible for regulating the current and voltage output. The control circuit is responsible for monitoring and regulating the output voltage and current. It receives input from the feedback circuit via a sense resistor, which is used to monitor the output voltage. The filter inductor is used to reduce the amount of high-frequency noise that is generated by the switch, and the output capacitor further stabilizes the output voltage. The output diode protects the converter from the power being pumped back into the input supply. In conclusion, the VI-25W-EW series DC-DC converters are ideal for numerous applications that require up to 25 watts of output power. This series is equipped with a wide range of standard features such as wide input range, low noise, high efficiency, and over-voltage protection. The applications of this series include industrial, medical, automotive, communication equipment, and battery applications. The working principle of this series is based on a switch-mode control scheme that is regulated by the control circuit. The main components of this series consist of the input voltage sensing circuit, the switch, the control circuit, the feedback circuit, the filter inductor, the output capacitor, the output diode, and the sense resistor. The VI-25W-EW series is a great option for many applications that require high efficiency and low EMI output..
