DC-DC converters provide a reliable power source for a variety of applications. The VI-2NF-MX-F4 is one example of such a converter, designed to provide a stable output voltage from a wide input range. It features a high efficiency figure and low-noise power factor correction (PFC).

The VI-2NF-MX-F4 is a high-conversion-efficiency DC-DC converter with a wide input voltage range. It has an input power supply range of 18 to 36V and an adjustable output voltage of 1.5 to 15V. This makes it suitable for applications such as automotive power supplies, portable devices, and industrial automation. The converter is designed with high-performance components, such as shielded coils and low-temperature-inductance ceramic capacitors, to minimize heat buildup and ensure high reliability.

The VI-2NF-MX-F4 offers a wide range of features to support its application. Most notably, it features a high-efficiency (90%) ratio of output to input. The efficiency is achieved through the use of a fully synchronous rectifier to achieve maximum power conversion and low no-load power consumption. The converter also has a high power density, making it a good choice for applications where size and weight are considerations.

The VI-2NF-MX-F4 also uses an active power factor correction (PFC) circuit to minimize noise emitted by the power supply in the presence of power harmonics. PFC helps the converter operate more efficiently while keeping the noise level down. PFC is also used to reduce the Input Current Harmonics Distortion (IHD). IHD is an issue that is commonly encountered in some common applications, such as PCs and power supplies for consumer electronics. By reducing IHD, the converter can reduce the burden on equipment, which can lead to enhanced system reliability.

In order to ensure efficient and reliable power delivery, the VI-2NF-MX-F4 uses a half-bridge control topology that offers a wide input voltage range, low output voltage ripple, and fast dynamic response. The output voltage ripple is further reduced by using an International Rectifier’s patented Active Peak-Current Mode control circuit, which adapts the output voltage according to its load level. This ensures that the voltage is always within the range specified by the customer.

In addition to its features, the VI-2NF-MX-F4 has a wide range of protection features such as over-voltage, over-temperature, over-current, and under-voltage protection. These protection features help ensure a safe operating environment for the converter.

The VI-2NF-MX-F4 is suitable for a wide range of applications, from automotive power supplies to industrial automation, due to its wide input voltage range, high-efficiency rating, and low-noise power factor correction. The converter\'s high power density makes it a good choice for space-constrained applications, and the variety of protection features ensure that the converter is run safely and reliably.
