PMIC - AC DC Converters, Offline Switchers has seen rapid development in recent years, with the technological advances that have been made in the field. One of such products is the BD7672BG-GTR, which is an offline switcher that offers high efficiency and excellent noise characteristics. In this article, we will look at the application field and working principle of BD7672BG-GTR.

Application field of BD7672BG-GTR

This product is an offline switcher specially designed to use in telecom and networking applications, such as xDSL power supplies, FTTx, PoE, and other Ethernet and data communication systems. It can also be used for industrial automation systems, the main applications being commercial power supplies, LED lighting products, and UPS systems. This product is able to deliver superior performance in most of these applications owing to its excellent efficiency and simple design.

Working principle of BD7672BG-GTR

Basically, the BD7672BG-GTR follows a push-pull type of operation, which eliminates the need for a large transformer. This helps to reduce the form factor of the product, while increasing its efficiency and performance. The device is designed with an array of internal power MOSFETs and rectifiers, along with corresponding components, to achieve the push-pull operation. Furthermore, the product has selectable current mode control and output overvoltage and overcurrent protection.

The BD7672BG-GTR is able to sense a wide range of output current from 0.3A to 3A, and the voltage levels can range from 180V to 600V. The switching frequency of the device is set at 65kHz by default, which provides great noise reduction while maintaining an efficiency level of over 85%.

In comparison to traditional offline switchers, the BD7672BG-GTR also requires a much lower start-up current, typically around 2mA. This makes it very power efficient and helps to further enhance the performance of the product. Furthermore, the product comes with a wide range of features that make it an ideal choice for many applications.

Conclusion

To summarize, the BD7672BG-GTR is an excellent offline switcher that offers a great combination of performance, efficiency, and reliability. It is specially designed for use in telecom, networking, and industrial automation applications, and is able to deliver superior performance in all of these. The product has excellent noise reduction, low start-up current, and wide range of protections, making it perfect for the most demanding applications.
