凌特推出以太網(wǎng)供電接口控制器簡(jiǎn)化采用IEEE 802.3af標(biāo)準(zhǔn)的用電設(shè)備設(shè)計(jì)

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(shè)計(jì)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(shè)備到按照IEEE 802.3af標(biāo)準(zhǔn)供電的以太網(wǎng)。這供電電壓為－48V的接口控制器具備標(biāo)記電阻、可編程分級(jí)、電源開關(guān)、浪涌電流限制和故障保護(hù)等多項(xiàng)功能，極大地簡(jiǎn)化了用電設(shè)備的設(shè)計(jì)。LTC4257可與凌特公司的多種DC/DC轉(zhuǎn)換器直接連接，為IP電話、無線接入點(diǎn)和其他用電設(shè)備（PD）提供了具成本效益的電源解決方案。

引言許多通訊、服務(wù)器和其他應(yīng)用領(lǐng)域都需要多輸出電壓的隔離電源，但是對(duì)所有的輸出電壓都提供嚴(yán)密調(diào)節(jié)是令電源設(shè)計(jì)工程師們頭疼的事。一般的，設(shè)計(jì)者在每個(gè)輔助輸出端加一個(gè)線性調(diào)節(jié)器，但線性調(diào)節(jié)器的效率非常低，限制了它的低輸出電流應(yīng)用。另一個(gè)選擇是用一個(gè)降壓轉(zhuǎn)換器作為后調(diào)節(jié)器。這種方法有較好的效率，但是如果后調(diào)節(jié)器在初級(jí)輸出端級(jí)聯(lián)的話，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)副線圈的話將需要附加的整流器、電感和電容器。附加的電源轉(zhuǎn)換級(jí)和元器件增加了傳導(dǎo)損耗。另一個(gè)選擇是用磁放大后調(diào)節(jié)器，它的效率很高，特別是
