CN3300不是款任務于4.5V到32V的PFM升壓型多節手機電池電動車充電合理ibms電源線路。 CN3300使用涓流，恒流和準恒壓事態(Quasi-CV^TM)對電(dian)池(chi)停此電(dian)動車充(chong)電(dian)申辦(ban)，里(li)面結構一(yi)體化有基準線端電(dian)壓源，電(dian)感功率的檢測企事業(ye)單(dan)位，吃妻上(shang)癮控制電(dian)路系統(tong)和(he)片外場定(ding)律單(dan)晶體管(guan)驅使控制電(dian)路系統(tong)等，享(xiang)有里(li)面結構元器件封裝少，利用率簡潔等自(zi)己的優(you)點。

當(dang)(dang)接聽電(dian)(dian)(dian)(dian)(dian)(dian)話輸(shu)入(ru)輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)源適配器后(hou)，CN3300邁(mai)入(ru)續(xu)(xu)航(hang)狀(zhuang)態，合理片外(wai)N溝(gou)道MOSFET導通，電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)流大(da)小回落，當(dang)(dang)回落到(dao)(dao)(dao)(dao)(dao)內層電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)流大(da)小查(cha)重(zhong)熱敏電(dian)(dian)(dian)(dian)(dian)(dian)阻安(an)裝的(de)最大(da)值(zhi)時(shi)，片外(wai)N溝(gou)道MOSFET退出(chu)，電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)感(gan)(gan)(gan)應電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)大(da)小降(jiang)低，電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)中的(de)能量消耗遷移(yi)到(dao)(dao)(dao)(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組中。當(dang)(dang)電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)感(gan)(gan)(gan)應電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)大(da)小降(jiang)低到(dao)(dao)(dao)(dao)(dao)內部管理感(gan)(gan)(gan)應電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)大(da)小論(lun)文檢測電(dian)(dian)(dian)(dian)(dian)(dian)阻值(zhi)放置(zhi)的(de)次(ci)數時(shi)，片外(wai)N溝(gou)道MOSFET二次(ci)導通，如斯(si)天道輪(lun)回。當(dang)(dang)FB管腳(jiao)(jiao)電(dian)(dian)(dian)(dian)(dian)(dian)流1次(ci)來到(dao)(dao)(dao)(dao)(dao)1.205V(楷模值(zhi))時(shi)，CN3300進來準恒壓(ya)(ya)筆記本續(xu)(xu)航(hang)形勢，以較(jiao)小電(dian)(dian)(dian)(dian)(dian)(dian)流值(zhi)對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)板筆記本續(xu)(xu)航(hang)。只(zhi)要是當(dang)(dang)FB管腳(jiao)(jiao)電(dian)(dian)(dian)(dian)(dian)(dian)阻第二種次(ci)來到(dao)(dao)(dao)(dao)(dao)1.205V時(shi)，快充(chong)的(de)進程才(cai)竣事(shi)，片外(wai)N溝(gou)道MOSFET努力(li)立即(ji)停止概(gai)況。在(zai)筆記本充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)竣事(shi)概(gai)況，當(dang)(dang)FB管腳(jiao)(jiao)輸(shu)出(chu)功率下落到(dao)(dao)(dao)(dao)(dao)再(zai)續(xu)(xu)航(hang)域值(zhi)時(shi)，CN3300再(zai)者打開(kai)e充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)壯況。CN3300至高目標頻度達到(dao)(dao)(dao)(dao)(dao)1MHz，任(ren)何體溫大(da)規模從－40℃到(dao)(dao)(dao)(dao)(dao)＋85℃。
