140CPS11420 交流电源模块 集成电路(IC)

产品描述

一般来说，这类模块称为负载(POL)电源供应系统或使用点电源供应系统(PUPS)。由于模块式结构的优点甚多，因此模块电源广泛用于交换设备、接入设备、移动通讯、微波通讯以及光传输、路由器等通信领域和汽车电子、航空航天等。

尤其近几年由于数据业务的飞速发展和分布式供电系统的不断推广,模块电源的增幅已经超出了一次电源。模块电源具有隔离作用，抗干扰能力强，自带保护功能，便于集成。随着半导体工艺、封装技术和高频软开关的大量使用,模块电源功率密度越来越大;转换效率越来越高,应用也越来越简单。

电源模块

人们在开关电源技术领域是边开发相关的电力电子器件，边开发开关变频技术，两者相互促进推动着开关电源每年以超过两位数字的增长率向着轻、小、薄、低噪声、高可靠、抗干扰的方向发展。开关电源可分为AC/DC和DC/DC两大类，DC/DC变换器现已实现模块化，且设计技术及生产工艺在国内外均已成熟和标准化，并已得到用户的认可，但AC/DC的模块化，因其自身的特性使得在模块化的进程中，遇到较为复杂的技术和工艺制造问题。

Product description

In general, such modules are called load (POL) power supply systems or point-of-use power supply systems (PUPS). Because of the advantages of the modular structure, the module power supply is widely used in switching equipment, access equipment, mobile communication, microwave communication, optical transmission, routers and other communication fields and automotive electronics, aerospace and so on.

Especially in recent years, due to the rapid development of data services and the continuous promotion of distributed power supply systems, the increase of module power supplies has exceeded the primary power supply. The module power supply has the function of isolation, strong anti-interference ability, built-in protection function, easy to integrate. With the extensive use of semiconductor technology, packaging technology and high frequency soft switch, the power density of module power supply is increasing. The conversion efficiency is getting higher and the application is getting simpler.

Power module

People in the field of switching power supply technology is the development of related power electronic devices, the development of switching frequency conversion technology, the two promote each other to promote the switching power supply every year with a growth rate of more than two digits to light, small, thin, low noise, high reliability, anti-interference direction. Switching power supply can be divided into AC/DC and DC/DC two categories, DC/DC converter has been modular, and the design technology and production process at home and abroad have been mature and standardized, and has been recognized by users, but the modularization of AC/DC, because of its own characteristics in the process of modularization, encounter more complex technology and process manufacturing problems.
