VI-20H-EY-F1

DC-DC converters are electrical devices that convert power from one direct current source to another, enabling the user to modify the voltage or current of the output to better meet their needs. One of the most popular and effective DC-DC converter solutions is the VI-20H-EY-F1 by VICOR Corporation.

The VI-20H-EY-F1 offers a very high efficiency of 95.8%, making it ideal for applications such as medical equipment, communications systems, and industrial test and measurement that require a clean, stable DC output. It is also designed with a switching frequency of 300-400kHz, allowing it to be used in high-frequency applications.

The VI-20H-EY-F1 accepts input voltages ranging from 9-36V, providing two isolated outputs of 12V and 18V with a total output power of up to 240W. It also operates at a wide temperature range of -40°C to 115°C and offers both standard and custom output configurations. In addition, the VI-20H-EY-F1 also features short circuit, over voltage, and over temperature protection for improved safety.

The working principle behind the VI-20H-EY-F1 is fairly straightforward. It uses a high frequency switching power converter circuit and a full-bridge rectifier to convert the input voltage into a regulated DC output voltage. The switching power converter circuit is composed of two MOSFETs, an inductor, and a high frequency operating switch.

The high frequency operating switch\'s switching speed is regulated by the input voltage and the required output voltage and forms the heart of the DC-DC conversion process. The rectifier then takes the voltage and current from the output of the switching circuit and converts it to a DC output with stable voltage and current levels. The VI-20H-EY-F1 also includes integrated voltage and current compensation, allowing it to be used for applications where the output voltage or current needs to be adjusted.

Overall, the VI-20H-EY-F1 is an ideal DC-DC converter solution for applications that require efficient power conversion, wide temperature range and high-frequency operation. It offers a wide input voltage range of 9-36V and is capable of providing two isolated outputs with a total power output of up to 240W. In addition, the VI-20H-EY-F1 also includes integrated protection for short-circuit, over voltage, and over temperature.
