日前，Silicon Labs(亦称“芯科科技”)发布了两款全新的以太网供电(PoE)受电设备(PD)系列产品，为各种物联网(IoT)应用提供一流的集成度和效率。Silicon Labs的Si3406x和Si3404系列产品在单个PD芯片上包含了所有必要的高压分立元件。新的PD IC支持IEEE 802.3 PoE+受电能力、效率超过90%的灵活的电源转换选项、强大的睡眠/唤醒/LED支持模式以及出色的抗电磁干扰能力。这些功能可帮助开发人员在高功率、高效率PoE PD应用中降低系统成本且加快产品上市步伐。
New PD IC support IEEE 802.3 PoE + by capacity, more than 90% of the flexible power conversion efficiency options, powerful sleep/wake/LED support model as well as excellent resistance to electromagnetic interference ability.These functions can help developers reduce system costs and speed up product launch in high power and efficient PoE PD applications.
IoT的快速扩张正在推动IP摄像机、智能照明灯具、功能丰富的视频IP电话、先进的802.11无线接入点和智能家电等应用对于PoE+连接的需求。这些需要更高功率的应用驱动了对于支持PoE+标准的PD器件的需求增长。例如，带有云台/变焦和加热元件的最新电机定位IP摄像机会对电源造成严重的负载。PoE+技术带来30瓦的输出功率，从而能够支持这些苛刻的应用任务。Silicon Labs的Si3406x系列产品适用于家居、商业和工业环境，是新型PoE+使能的IoT产品的理想PD接口解决方案。
The PoE+ technology delivers 30 watts of output power to support these critical application tasks. The Si3406x series of Silicon Labs is suitable for home, commercial and industrial environments, and is the ideal PD interface solution for the new PoE+ enabling IoT products.The rapid expansion of IoT is driving the demand for PoE+ connections with IP cameras, smart lighting, feature-rich video IP phones, advanced 802.11 wireless access points, and smart appliances. These higher power applications drive demand growth for PD devices that support the PoE+ standard. For example, the latest motor positioning IP camera with a cloud platform/zoom and heating element causes a serious load on the power supply.
Silicon Labs电源产品副总裁Ross Sabolcik表示：“Silicon Labs的PoE解决方案提供高达30瓦的多种功率等级，满足客户苛刻的电源需求。我们的PD产品组合带来业界领先的集成度和先进功能，帮助开发人员简化设计，同时满足其功耗和成本预算。Silicon Labs的一站式PoE产品可同时满足以太网电缆两端的应用需求，此产品组合包括新型的PD器件，以及PSE控制器和PSE电源管理IC。”
