VI-22J-MX-S

DC–DC converters are devices that take in an input DC voltage and output a different DC voltage.The VI-22J-MX-S is a DC–DC converter with an adjustable voltage output. It is suitable for applications that require a voltage between 1.2 and 16 VDC under input voltages of between 14 and 53 VDC.

Applications

The VI-22J-MX-S is a non-isolated DC–DC converter and has numerous applications. It is often used as a power supply in audio amplifiers and automotive systems, both of which require an adjustable input voltage. It is also suitable for applications that involve precision instruments, such as alarm systems and motor control systems.

Working Principle

The VI-22J-MX-S is a classic buck–boost switching regulator. The input voltage is stepped up or down accordingly to generate the required output voltage. This is done by a step-up transformer which charges the DC input into an AC voltage. A DC–DC switching regulator then converts the AC output from the transformer into a DC output.The voltage is regulated by an internal voltage regulator. This voltage regulator works by comparing the internal reference voltage (1.2 V) with the output voltage. When the output voltage rises above the reference voltage, it signals the DC–DC switch to break, which then reduces the output voltage. Conversely, when the output voltage drops below the reference voltage, it signals the DC–DC switch to close, which then increases the output voltage.

Conclusion

The VI-22J-MX-S is a non-isolated DC–DC converter that can be used in a variety of applications, from audio amplifiers and automotive systems to precision instruments and motor control systems. It is a buck–boost switching regulator that works by step-up or step-down the input voltage to generate the required output voltage. The voltage is regulated by an internal voltage regulator which compares the reference voltage to the output voltage.
