DC DC Converters are devices used to convert an electrical signal from one DC voltage level to another. The V72B28E250BN3 module is a common DC-DC converter used in applications that require a precise output. This module has several features that make it an attractive choice for a wide range of applications. In this article, we will discuss the application field and working principle of the V72B28E250BN3.

Application Field

The V72B28E250BN3 is a high-efficiency Miniaturized DC/DC converter designed for a wide range of applications including driving logic circuits, MEMS structures, telecom systems, and other low-voltage circuits. Internally, it has built-in over-voltage, under-voltage, over-current, and thermal protection. The wide input voltage range of 4V to 28V DC and output voltage range of 0.8V to 25V DC make it suitable for a variety of transportation or industrial applications. Additionally, it has a high efficiency of up to 92% and maximum output current of 2.1A - making it ideal for high-energy applications.

Working Principle

The V72B28E250BN3 is a dual-channel synchronous buck converter, meaning that it takes in two voltages and converts them into a single voltage output. This module has two independent switching ICs – one for each of the input voltages. As the two voltages enter the module, they are regulated and buck-converted into a single regulated voltage. The voltage output is then filtered and regulated for use.

The V72B28E250BN3 module also features an adjustable soft-start function, allowing the user to more precisely control the output voltage. This feature helps to reduce the inrush current at startup, which in turn can reduce the chances of the output voltage dropping and damage to components. Additionally, the module supports both positive and negative logic, with a maximum frequency of 500KHz.

Conclusion

The V72B28E250BN3 module is a high-efficiency synchronous buck converter, designed for a wide range of applications. It has a wide input and output voltage range, making it suitable for many transportation and industrial applications. Additionally, it features adjustable soft-start and over-voltage and under-voltage protection, making it an attractive choice for a variety of projects.
