VE-25V-EY-F4

DC DC Converters

A DC DC converter is a device which converts a direct current (DC) input to a different direct current output voltage. It is often used to interface different types of electrical circuits, such as between computer systems and communications equipment. The most common type is a switching regulator, which is a device that converts a fixed input voltage to a variable output voltage at a constant frequency, usually by switching the input off and on thousands of times per second.

VE-25V-EY-F4 Application Field and Working Principle

The VE-25V-EY-F4 is a high efficiency DC DC converter manufactured by Vicor Corporation. This converter is capable of operating on an input voltage range of 6-48VDC, and provides a dual output voltage of +/-25V. It is used in a variety of industrial, automotive, military and communications applications, and is well-suited to applications requiring the conversion of one type of DC voltage level to a different DC voltage level. It is also commonly used in battery-powered systems where the output voltage must be higher than the available battery voltage.

The VE-25V-EY-F4 is a switching regulator, and works by controllably switching the input voltage on and off at fast speeds, typically in the range of a few hundred kilohertz. The output voltage is regulated by controlling the duty cycle of the on and off times. By rapidly switching the input voltage on and off, the converter efficiently converts the voltage to the desired output levels. Additionally, the VE-25V-EY-F4 has a frequency control feature that allows for the frequency to be adjusted, allowing the output voltage to be set to a precise voltage.

The VE-25V-EY-F4 also has a number of other features that help with power efficiency. These include active high-side and low-side peak current limiters, an overvoltage protection circuit, and a maximum power point tracking feature that allows the converter to operate in the most efficient power range. Additionally, the converter includes a power-good signal, which indicates when the output voltage is within the acceptable range.

Overall, the VE-25V-EY-F4 is an efficient, reliable, and feature-rich DC DC converter that makes it an ideal solution for a variety of industrial and automobile applications. It is capable of providing a precisely controlled voltage, and is well-suited to a variety of power conversions.
