以太網(wǎng)供電 (PoE) 設(shè)備

Si3404 是業(yè)內(nèi)集成度最高、符合 IEEE 802.3 條款的類型 1 合規(guī)、PoE PD 接口和脈沖寬度調(diào)制 (PWM) 開關(guān)穩(wěn)壓器。通過設(shè)置新的欄實現(xiàn)設(shè)備集成、最低整體 BOM 成本、效率和可靠性，Si3404 可讓設(shè)計人員輕松將 PoE 功能添加到其以太網(wǎng)產(chǎn)品中。當納入諸如無線接入點或 VoIP 電話等啟用了 PoE 的系統(tǒng)中時，Si3404 可將以太網(wǎng)銅質(zhì) UTP 布線提供的高電壓（通常 ±48 V）轉(zhuǎn)換為穩(wěn)定的低壓直流電源。此外，Si3404 將所有必需的 IEEE 802.3 條款的類型 1 檢測、分類和熱插拔接口與一個完整、高效的 PWM 開關(guān)穩(wěn)壓器結(jié)合起來。簡單增加輸入二極
