DC DC Converters

DC DC converters are electrical circuits which employ electronic devices to convert a source of direct current (DC) from one voltage level to another. They are commonly used in many applications such as power supplies, motor control and sensor circuits. The VI-B74-IY-F1 DC DC converter is a highly efficient DC power converter designed for use in harsh environments such as rugged and extended temperature applications. This paper will discuss the VI-B74-IY-F1’s application field and its working principle.

Application Field

The VI-B74-IY-F1 DC DC converter is used mainly in applications that require highly efficient operation at extreme temperatures, such as spacecraft, avionics, military, and industrial applications. It has been designed to provide a high power density in a variety of form factors to meet the needs of these applications. The VI-B74-IY-F1 is rated for continuous operation of up to 1.5 W at full load and up to 100 W at peak load.

The VI-B74-IY-F1 offers excellent electrical parameters, including a wide operating input voltage range, high regulation accuracy, and a regulated output voltage. Moreover, the VI-B74-IY-F1 is designed for reliable operation in extended temperature range of -40°C to +125°C.
