电源管理是连接的关键
随着网络连接性向越来越多的设备普及，高速数据和高速电源的能力至关重要。动态电源的控制，特别是新的低电压工作模式，要求设备对其总电源进行交互控制。这包括充电器和DC-DC转换器的多个功率电平，当联网接口被使用或闲置时。
将IEEE 802.3标准纳入设计中，不仅影响了数据头的设计，而且影响了整个设计，以处理峰值功率管理。本文将研究控制器集成电路和外围设备，用于将现有设计改造为这些新标准。这些电源解决方案存在于嵌入式设计和系统级。
Need for power management
Networking products， unlike most compuTIng equipment， fall into the infrastructure category. This means that the products and capabiliTIes need to be accessible not only on a 24/7 basis but also in all locaTIons. This need for 24/7 availability started when the uTIlization of the resources was also on a 24/7 basis. As computing has increased in speed and data rates have similarly risen， the networking devices no longer see a continuous flow of traffic. This packet-traffic-based flow impacts both the peak power utilization of the PHY for the network connections， as well as the baseline power response of the systems.
