VI-21Y-MX-F3

DC DC Converters

DC DC converters are voltage or current converters that can transfer electrical energy from one power source to a device that requires a different voltage or current level. These converters are typically used in applications that require a very small and low power voltage source, such as microcontrollers or sensors.

One type of DC DC converter that is often used is the VI-21Y-MX-F3. This converter uses a full-bridge, Asymmetrical Control, LLC (ACLLC) topology to transfer energy from a primary source, such as a high voltage or high frequency source, to a secondary source, such as a lower voltage.

Application Field

The VI-21Y-MX-F3 is commonly used in industrial and automotive applications that require a very small and low power voltage source. This DC DC converter is well-suited for automotive applications because of its high efficiency (98%), broad input voltage range (6 to 36 volts), and protection features. In addition, the VI-21Y-MX-F3 is designed for applications that require a very small size and form factor, such as the automotive infotainment, power supply, power management, and switching applications.

Working Principle

The VI-21Y-MX-F3 utilizes an Asymmetrical Control, LLC (ACLLC) topology to efficiently transfer power from a high voltage input to a low voltage output. This topology works by using an asymmetrical sequence of pulses that are applied to the two switches of the full-bridge converter. The voltage through the two switches can be adjusted to match the input voltage and the output voltage, which allows for high efficiency and a very low total harmonic distortion.

In addition, the VI-21Y-MX-F3 also features protection features such as over-temperature protection and over-voltage protection that protects the converter from potential damage.

Overall, the VI-21Y-MX-F3 is an ideal DC DC converter for applications that require a high efficiency, a very small size, and a low power voltage source. It is well-suited for industrial and automotive applications, such as the power supply, power management, and switching applications.
