使用电源模块简化低EMI设计

Simplifying EMI design using power modules

电源模块已包括FET和电感器,使得创建和完成具有良好EMI特性的电源设计变得简单而又快捷。使用降压模块进行设计时,最关键的是一些外部元件的放置方式,这有助于显著提高EMI特性。

The power module is composed of FET and inductors,making power designs with good EMI features simple and efficient.When step-down modules are adopted,the placement mode of some external components is the most critical,since it can help to significantly improve EMI features.See the main text.
