It is designed for high efficiency with up to 95% peak efficiency, and up to 92% efficiency over a wide input voltage range. Thanks to its small size and low profile, it can be easily mounted in narrow or small spaces. It also offers excellent thermal performance with no additional cooling required. It also includes features such as over-temperature protection and an adjustable output voltage range.

Applications

The VI-202-IX-F3 converter has a wide range of applications. It is suitable for a variety of applications requiring DC-DC power conversion, including but not limited to industrial equipment, automotive systems, telecommunications, radar and navigation systems, medical devices, and aerospace.

Working Principle

The VI-202-IX-F3 converter utilizes synchronous rectification technology, in which a buck-type switching converter is used in combination with a separate synchronous rectifier circuit. The switching converter consists of a switching transistor, inductor, and diode, which are used to generate an output voltage proportional to the input voltage. The rectifier circuit is used to convert the AC output of the buck circuit to a DC voltage.

The main output voltage of the converter is regulated by adjusting the duty cycle of the switching transistor, which is achieved by using a dedicated controller. The controller monitors both input and output voltages and current, and adjusts the switching frequency accordingly. In this way, the output voltage of the converter is regulated to remain constant, even when the input voltage and load are changing.

Conclusion

The VI-202-IX-F3 is a DC-DC converter specifically designed for industrial and military applications. It offers high efficiency, wide input voltage range, and adjustable output voltage range. Thanks to its small size and low profile, it can be easily mounted in tight spaces. It is also suitable for a variety of applications, including but not limited to industrial equipment, automotive systems, telecommunications, radar and navigation systems, medical devices, and aerospace. Its working principle is based on synchronous rectification technology, which utilizes a switching converter in combination with a dedicated controller.
