DC-DC converters are used in a wide variety of applications to convert one DC voltage to a different DC voltage. In some cases, the output voltage needs to be higher than the input voltage, while in other cases, the output voltage must be lower than the input voltage. The V72B28T250BL is a DC-DC converter designed to convert a 72V DC input voltage to a 28V DC output voltage. It is commonly used in applications where low voltage DC power is required, including in electronic devices such as computers and medical equipment. This article will explain the basic working principle of the V72B28T250BL, and examples of its typical applications.

Working Principle

The V72B28T250BL operates according to the basic principles of DC voltage conversion. It begins with the input voltage, which can range from 66 to 90VDC. The incoming power is then converted into a higher voltage (190VDC) using a series of power-switching components, including MOSFET transistors and isolated transformers. Afterward, the high-voltage power is increased in frequency by an oscillator, and then converted into a low-voltage AC power using a pulse width modulator (PWM). Finally, the low-voltage AC power is converted back to DC and controlled using a feedback loop. This ensures that the output voltage is always 32VDC, which is then regulated and regulated further to 28VDC using an inductor. This 28VDC output power is then supplied to the device using the output connections.

Applications

The V72B28T250BL is ideally suited for applications requiring low voltage DC power. For example, it is used in popular laptops, cell phones, and other mobile devices; as well as in medical equipment such as infusion pumps. Its low voltage and high output current rating make it a perfect fit for many electronic applications. It can also be used as a power supply for LED lighting systems, as well as automotive applications. Its small size and low energy consumption also make it perfect for use in a variety of space-restricted applications.

Conclusion

The V72B28T250BL is highly versatile and capable of providing efficient and reliable power conversion for a wide variety of electronic applications. Its broad input voltage range makes it suitable for most commercial and industrial applications. Thanks to its compact size and low energy consumption, it is also ideal for mobile and space-restricted applications. Finally, its feedback loop ensures a consistently stable output voltage, making it a great choice for medical and LED lighting applications.
