日前，Silicon Labs(亦稱“芯科科技”)發(fā)布了兩款全新的以太網供電(PoE)受電設備(PD)系列產品，為各種物聯網(IoT)應用提供一流的集成度和效率。Silicon Labs的Si3406x和Si3404系列產品在單個PD芯片上包含了所有必要的高壓分立元件。新的PD IC支持IEEE 802.3 PoE+受電能力、效率超過90%的靈活的電源轉換選項、強大的睡眠/喚醒/LED支持模式以及出色的抗電磁干擾能力。這些功能可幫助開發(fā)人員在高功率、高效率PoE PD應用中降低系統成本且加快產品上市步伐。
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的快速擴張正在推動IP攝像機、智能照明燈具、功能豐富的視頻IP電話、先進的802.11無線接入點和智能家電等應用對于PoE+連接的需求。這些需要更高功率的應用驅動了對于支持PoE+標準的PD器件的需求增長。例如，帶有云臺/變焦和加熱元件的最新電機定位IP攝像機會對電源造成嚴重的負載。PoE+技術帶來30瓦的輸出功率，從而能夠支持這些苛刻的應用任務。Silicon Labs的Si3406x系列產品適用于家居、商業(yè)和工業(yè)環(huán)境，是新型PoE+使能的IoT產品的理想PD接口解決方案。
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電源產品副總裁Ross Sabolcik表示：“Silicon Labs的PoE解決方案提供高達30瓦的多種功率等級，滿足客戶苛刻的電源需求。我們的PD產品組合帶來業(yè)界領先的集成度和先進功能，幫助開發(fā)人員簡化設計，同時滿足其功耗和成本預算。Silicon Labs的一站式PoE產品可同時滿足以太網電纜兩端的應用需求，此產品組合包括新型的PD器件，以及PSE控制器和PSE電源管理IC。”
