具集成反激式控制器的高功率PoE PD接口

時至今日，以太網(wǎng)供電 (PoE) 技術(shù)仍在當(dāng)今的網(wǎng)絡(luò)世界中不斷地普及。由供電設(shè)備 (PSE) 提供並傳輸至受電設(shè)備 (PD) 輸入端的 12.95W 功率是一種通用電源

對于電源故障保護應(yīng)用，超級電容器能夠替代后備電池

在越來越多的短時間能量存貯應(yīng)用以及那些需要間歇式高能量脈衝的應(yīng)用中，超級電容器找到了自己的用武之地。電源故障保護電路便是此類應(yīng)用之一，在該電路中，如果主電源發(fā)生短時間故障，則接入一個後備電源，用於給負載供電

使用簡易閂鎖電路保護電源

設(shè)計時需要過一款簡單、低成本的閂鎖電路 (latch circuit) ？圖一顯示的就是這樣一款電路，基本上是一個可控矽整流器(SCR)，結(jié)合了一些離散組件，只需低成本的元件便可以提供電源故障保護。

DDR記憶體電源

CMOS 邏輯系統(tǒng)的功耗主要與時脈頻率、系統(tǒng)內(nèi)各閘極輸入電容及電源電壓有關(guān)，裝置尺寸縮小後，電源電壓也隨之降低，使得閘極大幅降低功耗。這種低電壓裝置擁有更低的功耗和更高的運作速度，因此系統(tǒng)時脈頻率可升高至 Ghz 範(fàn)圍。
