Definition
Communication base station power supply is one of the infrastructure of communication network, mainly responsible for providing stable and reliable power supply for various equipment in the communication base station. It includes a high frequency switching power supply and a battery pack.
Communication base stations are key facilities for wireless communication, such as cell phone towers, which are responsible for transmitting and receiving wireless signals so that people can make phone calls, send text messages and use mobile data. Therefore, the communication base station usually needs to be equipped with a backup power system to ensure that the communication base station can maintain normal operation in the case of the main power supply failure or power failure.
With the development of mobile communication network services to the direction of data and packet, the development trend of mobile communication base stations is also bound to be broadband, large coverage construction and IP. The market demand for base station power supply is also gradually increasing, among which, the performance improvement of the communication power conversion system comes from the reduction of the on-resistance of the high-voltage MOSFET, in order to achieve the current high-demand balanced energy efficiency goal, the market is also constantly pursuing more excellent performance MOSFET.
At present, for the full bridge, half bridge, LLC resonant switch and other applications, the Super-Junction MOSFET series products launched by Lamion Micro bring high energy efficiency to the extreme while maintaining reasonable power consumption, and comprehensively improve the switching characteristics and conduction characteristics of the device. In optimizing all key aspects of power supply, overall costs are reduced through functional upgrades and process technology optimization. At the same time, we provide you with a variety of package shape options including TO-263, TO-252, TO-220.TO-220F.TO-247.
