DC DC Converters

DC-DC converters are electrical devices that convert a direct current (DC) input voltage or current into a lower DC output voltage or current. A variety of configurations exist, including step-up, step-down, and inverting converters, as well as more complex designs like those based on switched-mode topologies with inductive and/or capacitive elements. The VI-26P-EY-F4 is a DC-DC converter with a adjustable voltage output range and various protections for surge and short-circuit protection.The VI-26P-EY-F4 DC-DC converter is designed to accept a wide range of input voltages, from 4.5 to 18 volts, and boost them to a regulated 24-volt output. The product is available as an adjustable or fixed voltage version with a pot adjustment mechanism, and is very efficient up to 90%. It has overvoltage, over-temperature, overcurrent, and short-circuit protection, as well as an adjustable soft start function.The VI-26P-EY-F4 DC-DC converter is suitable for use in a variety of applications, such as transportation, industrial, computer, telecommunications, consumer electronics, and instrumentation equipment, where reliability and stability of output power is critical. It can be used in systems where space is a concern because of its small form factor and low-profile design.The key to its operation lies in its regulating circuit, which comprises a voltage feedback loop and an error amplifier. This error amplifier compares the output voltage to its set-point values to generate an error signal. The error signal is then fed to the control element, a pulse-width modulated (PWM) booster regulator. As the converter’s input voltage varies, the PWM boost regulator adjusts the width of the output pulse to ensure a constant output voltage despite the variation in the input voltage.The VI-26P-EY-F4 is also equipped with a soft start feature that prevents inrush current and associated nuisance trips. The feature limits the maximum current the converter will draw from the power supply at start-up by ramping the output voltage gradually, reducing the risk of short-circuit and over-temperature protective trips.For optimal system performance, users should consider the operating temperature, input voltage range, load type, and output margins when selecting a DC-DC converter. The VI-26P-EY-F4 can adapt to a variety of input and output conditions to ensure reliable and efficient operation. It is easy to install and configure, with several options available to simplify integration and offer the best performance suited to any DC-DC conversion application.
