DC-DC converters can be found in almost any electronic device in many different power levels. This article will focus on the VI-JV1-MY-S DC-DC converters, describing their application fields and working principles.

VI-JV1-MY-S DC-DC converter is a high-efficiency converter module designed to increase power delivery across a wide range of voltage curves. It features rich protection functions, ultra high efficiency, long-term reliability, and comes in thirty different form factors. The VI-JV1-MY-S DC-DC converter is notably used for LED lighting, Railway Signaling, Mission Critical Automation, Professional Grade Networking, Industrial Automation, and Telecom Datacenter applications.

Working Principle

It is usually divided into two parts: input and output stage. The input stage accepts a DC voltage from the power source and converts it to an intermediate voltage. This intermediate voltage is then fed to the output stage, which further converts it to the desired voltage level. The VI-JV1-MY-S DC-DC converter has a dual-stage design that allows for higher efficiency and a much wider input voltage range.

In the input stage, an isolated power switch is used to control the power delivered from the source to the input capacitors. The switch is typically controlled by an external signal that is generated by the voltage regulator. During the on-time of the power switch, the input inductor accumulates energy while the output capacitors store energy. At the end of the regulation cycle the power switch is turned off, and the stored energy is transferred into the output stage.

The output stage of the VI-JV1-MY-S DC-DC converter utilizes a buck or boost topology that is designed around the output MOSFETs. The circuit design features a full bridge rectifier that allows for low-power start-up, which is important for any voltage converter. Furthermore, the output stage also provides a rich number of protection features such as over-voltage, over-current, and thermal protection.

Conclusion

The VI-JV1-MY-S DC-DC converters are a powerful and reliable solution for powering a wide range of applications. Their dual-stage design and full-bridge rectifier make them highly efficient and provide a wide voltage range support. Additionally, their protection features make them a great choice for mission critical and industrial automation applications.
