DC DC Converters

The VI-21R-EY DC-DC converter is a multi-function converter designed to power on equipment with a wide range of supply voltage requirements. This converter is simple to use and provides protection to the application, as well as a start-up and a continuous convergent current for the application’s input. The VI-21R-EY ensures reliability and control which greatly increases the stability and safety of the overall application.

Application Field

The VI-21R-EY DC-DC converters are a versatile and powerful tool in applications that require a lot of power but not much space. The VI-21R-EY can be used to build a variety of large scale projects due to its wide variety of input and output voltages and tolerances. These converters are ideal for converting very low voltage as well as very high voltage input to a desired output. This type of converter can be used in a wide range of consumer electronics, automotive, medical, industrial, and communications applications.

Working Principle

The VI-21R-EY is a non-isolated DC-DC converter. This means that the input voltage is directly converted to the output voltage without the need for a transformer or other isolation element. This converter\'s design results in the highest efficiency, up to 95%, in its class. The VI-21R-EY uses PWM (pulse width modulation) as the conversion control technique. This technique is used to encode a continuous analog signal so that it is able to switch a power amplifier or control an analog controller. During power on, the conversion of the input voltage is soft started and monitored by a power system detector. This immediately shifts the output to the pre-stored current then constantly regulates the current to keep the output voltage within the acceptable operating parameters throughout its application.

The VI-21R-EY also has protection features such as over-voltage protection, over-current protection, short-circuit protection, and temperature protection. These features ensure that the VI-21R-EY conducts operating conditions in a safe and efficient manner.

Conclusion

The VI-21R-EY DC-DC converter is an ideal choice when it comes to providing reliable and stable power. This converter is simple to use and can be used in a variety of applications. The VI-21R-EY is able to convert a wide range of input voltages and output voltages and tolerances. The protective features provide safety and stability for the application. The high efficiency and soft start capability also help to ensure optimum performance.
