凌特推出以太網(wǎng)供電接口控制器簡(jiǎn)化采用IEEE 802.3af標準的用電設備設計
- 日前, 凌特公司(Linear Technology)宣布推出以其業(yè)界領(lǐng)先的Hot SwapTM 技術(shù)而設計的LTC4257以太網(wǎng)供電接口控制器,這款器件實(shí)際上包含了所有必需的電路以連接用電設備到按照IEEE 802.3af標準供電的以太網(wǎng)。這供電電壓為-48V的接口控制器具備標記電阻、可編程分級、電源開(kāi)關(guān)、浪涌電流限制和故障保護等多項功能,極大地簡(jiǎn)化了用電設備的設計。LTC4257可與凌特公司的多種DC/DC轉換器直接連接,為IP電話(huà)、無(wú)線(xiàn)接入點(diǎn)和其他用電設備(PD)提供了具成本效益的電源解決方案。

多輸出隔離電源利用次級側同步后置穩壓器實(shí)現高效率
- 引言許多通訊、服務(wù)器和其他應用領(lǐng)域都需要多輸出電壓的隔離電源,但是對所有的輸出電壓都提供嚴密調節是令電源設計工程師們頭疼的事。一般的,設計者在每個(gè)輔助輸出端加一個(gè)線(xiàn)性調節器,但線(xiàn)性調節器的效率非常低,限制了它的低輸出電流應用。另一個(gè)選擇是用一個(gè)降壓轉換器作為后調節器。這種方法有較好的效率,但是如果后調節器在初級輸出端級聯(lián)的話(huà),電源需要一個(gè)更大的輸出電感和電容,或者如果用多個(gè)副線(xiàn)圈的話(huà)將需要附加的整流器、電感和電容器。附加的電源轉換級和元器件增加了傳導損耗。另一個(gè)選擇是用磁放大后調節器,它的效率很高,特別是
