　　智能功率控制应用中的MCU选择

　　电力供应继续提供新的功能，以提高效率，安全性和可管理性在苛刻的通信，工业和医疗应用。越来越多的MCU的智能电源的关键要素和实施大范围的控制、检测、管理功能。看看一些更先进的MCU硬件功能，以及它们简化智能电源设计的方法，对于任何使用嵌入式系统的硬件设计者都是有用的。

　　本文将介绍几个关键的MCU功能提供给嵌入式设计人员，解决智能电源的要求。在启动条件下的电源控制是一个明显的要求，但传感，测井和通信电源操作，也许是MCU的能力是最好的应用领域。

　　Reliability， safety， and efficiency

　　Today reliability， safety， and efficiency are the key customer concerns for most power supply subsystems. However， these requirements often conflict with the traditional concerns of low cost， small board space， and ease of design. Using an advanced MCU as the controller for an intelligent power supply design can help mitigate some of these conflicts to create a more optimized design. Modern MCUs pack significant capabilities in a small board space， with little cost and the availability of reference designs， code examples， and development platforms dramatically simplify implementation.

　　Usually the MCU needs some external supporting devices to complete the design. Finding the correct combination of the right MCU and the right external devices is key to efficient implementations. A quick look at some important on-chip MCU functions and some of the common external devices that pair efficiently with an MCU will help guide you to your own device selections for an efficient implementation based on your custom requirements.
