簡述：

CN3392就是款世界任務于2.75V到6.5V的PFM升壓型中秋國慶磷酸鐵鋰電池箱充電器放肆集合線路。 CN3392得到恒流和準恒壓形勢(Quasi-CV^TM)對手機微(wei)型蓄電(dian)(dian)池退出(chu)充(chong)電(dian)(dian)樁辦好， 外(wai)部集成(cheng)式(shi)有基準(zhun)面(mian)相工作電(dian)(dian)壓(ya)源，電(dian)(dian)感(gan)電(dian)(dian)流(liu)量檢(jian)則(ze)(ze)機關(guan)單位，手機微(wei)型蓄電(dian)(dian)池相工作電(dian)(dian)壓(ya)檢(jian)則(ze)(ze)用電(dian)(dian)線路和片(pian)內MOSFET等，要具備(bei)外(wai)部結構元器件封裝(zhuang)少，電(dian)(dian)路設計容易等憂點(dian)。

當撥打電(dian)(dian)(dian)(dian)(dian)話導(dao)出(chu)電(dian)(dian)(dian)(dian)(dian)壓后，CN3392進(jin)入到(dao)e充(chong)電(dian)(dian)(dian)(dian)(dian)現狀，規(gui)范片內N溝道(dao)MOSFET導(dao)通，電(dian)(dian)(dian)(dian)(dian)感交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)持(chi)(chi)續(xu)上升(sheng)，當持(chi)(chi)續(xu)上升(sheng)到(dao)外部結(jie)構交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)檢則(ze)電(dian)(dian)(dian)(dian)(dian)阻功(gong)率配置的進(jin)攻(gong)時，片內N溝道(dao)MOSFET中止(zhi)，電(dian)(dian)(dian)(dian)(dian)感直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)升(sheng)空，電(dian)(dian)(dian)(dian)(dian)感中的消耗的能(neng)量(liang)轉回到(dao)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池中。當電(dian)(dian)(dian)(dian)(dian)感直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)升(sheng)空到(dao)外接直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)測試熱敏電(dian)(dian)(dian)(dian)(dian)阻設有的限制時，片內N溝道(dao)MOSFET再(zai)導(dao)通，如(ru)斯(si)宿命。當BAT管(guan)腳的電(dian)(dian)(dian)(dian)(dian)壓最次(ci)達到(dao)間接裝置的8.4V(杰(jie)出(chu)值)時，CN3392步入準(zhun)恒(heng)壓電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)快充(chong)時局(ju)(ju)，以較小電(dian)(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)(dian)流(liu)對電(dian)(dian)(dian)(dian)(dian)瓶電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)快充(chong)。在準(zhun)恒(heng)壓時局(ju)(ju)，當BAT管(guan)腳輸(shu)出(chu)功(gong)率停(ting)靠8.4V時，充(chong)電(dian)(dian)(dian)(dian)(dian)樁系(xi)統進(jin)程(cheng)竣事，片內N溝道(dao)MOSFET維持(chi)(chi)關閉程(cheng)序概況(kuang)。當BAT管(guan)腳的電(dian)(dian)(dian)(dian)(dian)壓著陸(lu)到(dao)再(zai)電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)充(chong)電(dian)(dian)(dian)(dian)(dian)域(yu)值時，CN3392從(cong)新打開(kai)充(chong)能(neng)境(jing)況(kuang)。CN3392很高責任(ren)周(zhou)期會達1MHz。

當手機(ji)蓄電池輸送(song)功率達不到輸送(song)輸送(song)功率或手機(ji)蓄電池燒壞時，CN3392在片內N溝道MOSFET和(he)片外(wai)P溝道MOSFET的(de)積極配合(he)感召下，用較小電壓不間斷對鋰電池充(chong)電電動車充(chong)電，對鋰電池充(chong)電更好地發揮(hui)無球感召。

此(ci)外效果涉及到處理(li)器(qi)使能打印(yin)工作輸(shu)出，管芯過溫掩(yan)體，直流電探測電容虛(xu)接掩(yan)體和實力唆使打印(yin)工作輸(shu)出端等。

CN3392得到3mmⅹ3mm的(de)12管腳DFN芯片封裝。
