如何降低待机能耗ON Semiconductor

简介：

问：如果有遥控电路要工作 你们的IC提供多大的电流 5V的 还有现在功耗还能降到多个，对于电源自身工耗 谢谢！
答： That depend on your 5V current under standby, usually, if IR remote system, the current of MCU and IR sensor would use from 10mA to 30mA, any of ours IC could provide this.
But if yours circuit is RF remotor and many of other processor could not entry

问：降低待机功耗，IC起到很重要作用。除此之外，它还和什么因素有关？比如变压器，阻容元件？
答： A good control IC is the key to the solution, however you can"t realise it without good quality transformer, and capacitors.

问：除了芯片以外，被动元件的选择对待机功耗的影响有多大？ON对选择被动元件有何建议？
答： That"s quite depends on different application and working mode.
Normally, under standby mode, the high voltage side has bigimpact on standby power, that not only need controller to decrease working current and leackage , but also need some of pass

问：Q1:待机功耗与电源功率以及频率有何关系？
Q2:目前国际标准要求待机功耗是多少？现在实用电源的最低待机功耗是多少？
Q3:国际上有那几种方法实现待机？哪种最先进？
答： Q1. In SMPS, switching loss plays an important role, lowering the switching freq. can reduce switching loss.

Q2. It depends on what products and where to ship to.  For adaptors, IEA recommends 0.75W for adaptors, US President Bush reques

问：请问：安森美产品在解决了待机功耗问题后，其可靠性有没有提高，能提高多少倍？
答： There is no direct relationship.

问：安森美提供的应用示例是否可以直接用于产品设计？
答： Yes of course.

问：请问您公司提供的节能芯片能能在军品中使用不？主要是温度要求？
答： I am afraid ON does not make MIL grade products.

问：测量待机功耗是输入电压最大值还是最小值?
答： The standby power is tested at 220V typ.

问：我们公司正在开发的手持设备中用到了GSM模块，请问贵公司有没有相关GSM模块的电源管理芯片，可以尽量降低其功耗？可否提供相关的解决方案，谢谢！
答： Please send your requirement to manson.chan@onsemi.com.

We have other products to fit for hand-held products.

问：能否提供仿真软件
答： Some of our products already have the models and avaliable for free download in our website and we are trying our best to provide that for all our coming up products as well.
