VI-22Y-CV-F2

DC to DC converters allow electric current to be converted from one DC voltage to another. The VI-22Y-CV-F2 is a model of such a device from Vishay Intertechnology, a manufacturer of electronic components and semiconductors. It is made of four components: a step-up inductor, a power MOSFET, an active clamp circuit and a Zener diode. Below, we explore the field application of the VI-22Y-CV-F2 and its working principle.

Application Field

The VI-22Y-CV-F2 is designed for current-limited applications with a wide input voltage range of 16 to 65V. It is suitable for use in portable systems, medical and industrial equipment, which have a wide input voltage range but require a steady output voltage. This device is comprised of extremely low profile components which makes it desirable for applications with limited space. Additionally, it is designed to operate at high temperatures which makes it suitable for stable operation in extreme weather conditions.

The VI-22Y-CV-F2 also features a built-in current-limit circuit which limits the maximum output current from the converter. This allows the device to provide reliable and stable output voltage without sacrificing efficiency or output voltage accuracy. Finally, the device offers protection from overvoltage and reverse polarity connection.

Working Principle

The VI-22Y-CV-F2 works on the principle of voltage conversion. It takes in a high DC input voltage and converts it into a lower DC output voltage, with the help of four core components: an inductor, a power MOSFET, an active clamp circuit and a Zener diode. Let us look at how these components work together to performed the desired voltage conversion.

The inductor stores energy while the power MOSFET acts like a switch, allowing the stored energy to be released in a controlled manner. When the MOSFET is on, current flows through the inductor, resulting in a voltage increase. When the MOSFET is off, the voltage decrease. This process of alternating between on and off states helps achieve a step-up voltage conversion.

The active clamp circuit is used to reduce the amount of current flowing in the high side MOSFET to prevent it from reaching damaging levels. This ensures the safety of the device and prevents it from being damaged due to excessive current. The Zener diode helps protect the device from overvoltage and reverse polarity connection.

To conclude, the VI-22Y-CV-F2 is a model of a DC to DC converter designed for current-limited applications with a wide input voltage range. It consists of four components, a step-up inductor, a power MOSFET, an active clamp circuit and a Zener diode. Each of these components works together to achieve a stable output voltage and reliable power conversion. Lastly, the device is designed to protect itself from overvoltage and reverse polarity connection.
