DC/DC converters represent one of the most wide-spread power sources for both small and medium electronic loads. The VI-22V-IW series of converters are designed to meet specific demands with applications ranging from general low-power electronic equipment such as portable devices, toys, and computers, to portable power for railway and industrial automation. In this article, we will discuss the VI-22V-IW series of converters and their various application fields, as well as the working principle of the system.

VI-22V-IW application field

The VI-22V-IW series of DC/DC converters are designed for direct conversion of low voltage DC supplies to provide output voltages higher than the input. The VI-22V-IW converters are available in a number of different output voltages ranging from 12V to 22V, making them ideally suited for applications where the supply voltage is 5V or less and the load requires a higher voltage. They can be used to supply DC power to general electronics components such as cellular telephones, or be used in automotive applications such as radios or engine control systems.

The VI-22V-IW series also provides a high level of efficiency, ranging up to 95%. As a result, these converters are ideal for applications where space and power are limited, such as mobile devices. Additionally, the VI-22V-IW series offers a wide input range of 4.5V to 22V, making it suitable for use in a wide range of applications.

The VI-22V-IW converters are packaged in an industry standard SOIC package, making them easy to incorporate into existing designs. The SOIC package also features two low-noise Schottky rectifiers, which help to reduce the noise output from the converter.

VI-22V-IW working principle

The VI-22V-IW series of DC/DC converters uses a pulse width modulation (PWM) control technique, which allows for both low power losses and high levels of efficiency. This technique uses a current limited pulse-width modulator, which regulates the voltage output as a function of the input voltage. The VI-22V-IW converters use a combination of MOSFETs to convert the input DC. The MOSFETs are controlled by a current-limited PWM control circuit, which switches the devices on and off at a frequency of up to 1MHz, depending on the input voltage.

The VI-22V-IW series also uses a synchronous rectification technique in order to maximize efficiency. Synchronous rectification allows for the reduction of voltage losses by using the oppositely charging and discharging of the output capacitors during the switching cycles of the circuit. This allows for the output voltage to be higher than the input voltage, resulting in higher efficiency levels.

Conclusion

The VI-22V-IW series of DC/DC converters are designed to meet the specific requirements of small and medium electronics applications. These converters provide a high level of efficiency and a wide input voltage range, making them ideal for applications where space and power are limited. They also offer an industry standard SOIC package for ease of incorporation into existing designs. Finally, the VI-22V-IW series uses a PWM control technique combined with synchronous rectification to maximize efficiency by allowing for the output voltage to be higher than the input voltage.
