DC/DC converters are utilized for different applications, among them BWD2405 bewitch the market due its advantages. This article will discuss its application area and working principle, in order to have a better understanding of the product.

Introduction

BWD2405 is a high power, isolated, isolated buck DC/DC converter. It operates at ac input voltage range from 90 to 280 VAC, and provides a low output voltage range of 0.8 V to 15 V and a low output accuracy of 1 %. This product offers a high efficiency of up to 97 % under standard conditions, making it the prime candidate for applications requiring high power.

Application Field

BWD2405 has been widely used in batteries, ultra-low-power systems, industrial automation, automotive and energy storage systems. With its high power ability, it is ideal for applications that require power from low voltages up to 15 V. Its low power loss and excellent efficiency make it suitable for applications with tight power budget. Moreover, due to its high power rating, it is suitable for applications such as high-change PoE (Power over Ethernet) that require more than 25 W.

Furthermore, thanks to its high efficiency, this converter provides very good power quality. Its low temperature rise, low output ripple and noise and low turn-on surge make it very reliable option for situations when the environment or sensitive components should remain unaffected by voltage fluctuations.

The product can also be used for processes relying on software, such as FPGA, PCB or RPi (Raspberry Pi), as its low power loss allows it to operate at lower volatges with the same output power. This brings a great deal of flexibility to the process of design as the need of components can be reducted, resulting in lower cost.

Working Principle

The BWD2405 operates using the Buck Switching Regulator, which is considered the most commonly used DC/DC configuration. The Buck Switching Regulator or Buck Converter works by switching a transistor or other switch-like device to control the current flow.

To understand the operation, it is important to take a look at the different parts of the system. The most important parts of the system are the input power supply, the output capacitor, the switch, the inductor and the basic controller.

The input power supply is connected to the switch, which is turned off and on by the controller. The switch, when turned on, passes current to the inductor, which in turn charges the output capacitor.

The output capacitor retains the charge when the switch is turned off. At the same time, the energy stored in the inductor forces the current to keep flowing through the switch. The result is a steady output voltage, which is regulated by the controller.

Conclusion

To sum up, the BWD2405 buck DC/DC converter is suitable for applications needing up to 15 V, thanks to its high power rating and excellent efficiency. It is suitable for situations requiring high power, such as PoE applications or industrial and medical systems, as its low power loss reduce the amount of components needed. Its great power quality features make it even more suitable for applications that require stability and reliability.
