V375A2M160BF

DC-DC converters are invaluable for powering devices from multiple sources. Proprietary converters, such as the V375A2M160BF, are tailored to fit specific application requirements while also providing cost effectiveness. This article takes a look at the application fields and working principles of the V375A2M160BF.

Application fields

The V375A2M160BF is designed to convert the Wide Input Voltage Range from 10V–350V DC, to a maximum output voltage of 160V DC. It is fully isolated, so the input and output can operate at different levels. This specialty converter makes it ideal for applications requiring a wide range of input and/or output voltages. The V375A2M160BF has also proven useful in connection and disconnection service, EMI filtering, and dc-dc conversion.

High isolation is a necessary feature in many applications, such as those in the medical field which involve human contact. When facing high humidity and temperature, the V375A2M160BF maintains its efficiency and isolation despite the conditions. Additionally, its reduced size when compared to similar converters allows for a more compact design and thus ease of integration.

The V375A2M160BF has already seen successful use in automated test equipment, battery supplies, power monitoring systems, telecommunications, transportation, industrial control, and automotive applications. It can even be used in the field of robotics; its isolation feature makes it ideally suited to meeting a range of power requirements.

Working Principles

The V375A2M160BF works using a standard Single-Ended Primary-Inductor Converter (SEPIC) topology. It is an isolated buck-boost topology, where the output voltage is regulated regardless of whether it is higher or lower than the input. This SEPIC passive configuration does not have a power transistor switch operating, resulting in reduced power consumption.

The converter begins to operate when the switch is turned on. As current flows, an inductor is wound up with energy, and then the current is stored. As the switch is switched off, the inductor produces an electromotive force (EMF). This EMF helps to maintain the output voltage, as well as providing a boost action.

Though the voltage is initially boosted, the voltage then begins to decrease until a low-voltage trip occurs. This causes the converter to switch back on and restart the cycle, providing a continual output regulation. The V375A2M160BF then uses the output of the SEPIC for regulation, allowing the output voltage to be adjustable.

Conclusion

The V375A2M160BF DC-DC converter provides a variety of applications with reliable, and efficient power delivery. Its unique single-ended primary-inductor converter topology significantly reduces power loss, and high isolation in contact applications makes it an admirable choice for all safety-critical projects. With its wide range of input and output voltages, efficiency, and compact size, this converter has been finding success in a variety of industries.
