如何降低待机能耗ON Semiconductor

简介：

问：降低待机能耗需要多方面的努力,你能具体说说吗？
答： ON"s products provide very effective solution.  Please refer to our portfolio and application notes.

问：通过高电压技求降低待机能耗,在成本方面是否过高?
答： The cost is very competitive.

问：在AC输入端串接的共膜滤波器电感的参数选择是怎么样的？
答： Generally speaking, higher wattage power supply needs higher inductance common mode choke.  Its value should be in the range of 10mH to 47mH.  Higher inductance will affect the characteristic of the choke.  Therefore, some tim

问：开关变压器的参数设计，安森美有提供什么样的计算方式？
答： Right now we do have some tools, Excel, simulation models, etc. to help customer to calculate the transformers. We will keep on develope more and more to help around.  In case you have any needs, please send us a email see whether we can do somet

问：采用安森美芯片的产品，在电磁兼容性方面应该做什么样的处理？
答： Basicly, it should according to the normal EMC process to consider whole of circuit.

e.g.  PCB lay out, Transformer structure, line Input filtering SMPS working mode, sheilding...

Some of ours chip could secure the working mode

问：MC44608做成单端反激式电路能最大做成多大的输出？
答： The only limitation is the Flyback mode itself.
MC44608 could delivery over 200W to load. and if the input voltage range is smaller, it could be higher (e.g. using a kind PFC before it)

问：对于TV类产品（大约250W），待机功耗小于1W的方案有吗？
答： Yes, we have a new device NCP1209 that is designed for TV application.  Stanby power can meet less than 1W.

问：一个系统要降低功耗，一般应该从哪几方面来入手解决呢？
答： From the system point of view, not only talking about standby, efficiency is number one.  The first thing we need to do is making the system efficiency as high as possible. In order to do that, we need to identify where are the power loss gone, i

问：请问onsemi的节能产品有哪些适合在手机中的应用？
答： Yes, we do.  Please send your detail requirement to me,
