DC DC Converters

MGW304815-R is a kind of DC/DC converters which belongs to the family of power conversion devices. It is specially designed for communication systems with advanced performance, low power consumption and high efficiency. The micro-architecture of the device makes it well-suited for communication systems due to its capability of providing power for radio, antennas, and access points with continuous, uninterrupted operation.

Application Field of MGW304815-R

MGW304815-R is applicable to applications such as Wireless Infrastructure, Machine-to-machine (M2M) communication, Fixed Access Networks, Base Stations and many other communication systems for bi-directional converting. It have excellent thermal behavior that ensures system heating is within acceptable limits. MGW304815-R is also designed for easy implementation and assembly, and can easily be used in high-volume production. The device is sensitive to EMI, and is designed to meet the low-emission requirements for wireless communications applications such as WLAN, WiMax and WiPair.

Working Principle of MGW304815-R

The MGW304815-R adopts an isolated buck-boost converter topology which allows a wide input voltage range from 2.9V to 18V at the input side. Generally, the buck-converter will reduce the input voltage and transfer to output side while keeping its current constant and maintaining DC stability. However, the MGW304815-R can reach large ranges beyond its input voltage range, enabling more operating flexibility for various applications. On the output side, it has the capability to provide up to 15W of output power and a wide output voltage adjustment range (2.8V to 4.5V).The controller internalizes digital control loops and feedback circuits to provide accurate and absolute stable outputs, thereby preventing any electrical reliability issues due to operating conditions or temperature. This low power solution also features a hysteretic MOSFET which greatly reduces the power loss of upper MOSFETs and substantially increases the conversion efficiency while still providing an accurate output voltage. In addition, the MGW304815-R\'s switching frequency is optimized to reduce the no-load power consumption of the system which further increases the efficiency and contributes to lower total system cost.

Conclusion

MGW304815-R is a versatile DC/DC converter designed for high-precision and versatile power conversion needs. Its micro-architecture makes it suitable for any communication system and it can provide precision output independent of the input voltage and temperature. Its compact size and robust design allows easy integration into any system and its high power efficiency means its cost-effectiveness as well. With its efficient and reliable design, the MGW304815-R is an ideal choice for applications such as wireless infrastructure, M2M communication, and fixed access networks.
