DC–DC converters are electrical power converters that convert a source of direct current (DC) from one voltage level to another level. The VI-24D-IX-B1 is a DC–DC converter designed to provide 24V industry-standard input voltage to a regulated, isolated 5V output voltage in industrial, IT/telecom, medical and consumer applications. In this article, the application field and working principle of the VI-24D-IX-B1 DC–DC converter are investigated.

Application Field

The VI-24D-IX-B1 converter is designed to provide 24V industry-standard input voltage to a regulated, isolated 5V output voltage in industrial, IT/telecom, medical and consumer applications. It is designed specifically for applications such as industrial Ethernet switches, medical devices and consumer-electronic products. It is also suitable for systems needing a high-performance, isolated 5V output.

The VI-24D-IX-B1 has excellent features ideal for a wide range of applications. It has a 2:1 input voltage range of 18–36V and a regulated 5V output voltage. It also has a programmable switching frequency from 550 kHz to 1350 kHz, enabling maximum flexibility for design optimization. The converter has a very high efficiency of 85% at full load. It is also able to survive 5V transients without any additional components.

Working Principle

The VI-24D-IX-B1 converter has a flyback topology, which essentially involves switching the output voltage at a high frequency so that high voltage on the output is obtained. The converter converts the 24V input voltage into a higher output voltage using a transformer to isolate the input from the output and provide electrical insulation. The converter switches the output voltage, using an integrated high-side switch, at a frequency with a duty cycle that is controlled by feed-forward and error-sensing circuits. The converter then uses an inductor to store energy when the switch is on and output the energy when the switch is off. The output voltage is then rectified and regulated to the required 5V output, ensuring consistent output even during wide input voltage and load variations.

The VI-24D-IX-B1 utilizes several design features that make it a very efficient converter. It has a reduced component count, enabling a sleek design and a decrease in overall board space. It also has an optional bypass-mode feature that allows for a start-up at low power levels. In addition, it has a built-in low-battery alarm and can detect an over-current condition and then shuts down itself automatically to prevent damage.

Conclusion

The VI-24D-IX-B1 DC–DC converter is an ideal solution for industrial, IT/telecom, medical and consumer applications that require a regulated, isolated 5V output voltage from a 24V input voltage. It is capable of meeting a wide range of requirements with its ability to provide a high-performance, isolated output. In addition, its flyback topology makes it very efficient, while its reduced component count enables a sleek design. As such, the VI-24D-IX-B1 is the perfect choice for any application requiring a reliable DC–DC converter with24V input voltage and 5V output voltage.
