線性充電器和開關充電器廣泛應用于多種應用：助聽器、智能手表、傳感器節點、手機、筆記本電腦...數不勝數！每當使用可充電電池時，都需要一個充電器。那么我們該如何在二者中選擇呢？接下來電(dian)源(yuan)適配器(qi)廠家就來教大家如何判斷。

每種方法都有其(qi)利(li)弊。線性充電(dian)器(qi)體積小、易于使用(yong)(yong)、成本低廉(lian)。不用(yong)(yong)任(ren)何(he)切換，它們即(ji)可適(shi)用(yong)(yong)于噪(zao)聲敏感的應用(yong)(yong)；但是(shi)當充電(dian)電(dian)流大時，功(gong)耗很(hen)高。開關充電(dian)器(qi)以其(qi)高效率(lv)而(er)聞名，并可在(zai)輸入適(shi)配器(qi)電(dian)壓的廣泛變量下(xia)最小化功(gong)耗。但與線性充電(dian)器(qi)相比，附加電(dian)感器(qi)和電(dian)容(rong)器(qi)消耗更多的電(dian)路板空(kong)間(jian)，增(zeng)加了BOM成本和設(she)計復雜性。

我們可以看(kan)一下二者的比較

線性充(chong)(chong)電(dian)(dian)(dian)器：功(gong)耗大，充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)大；簡單(dan)設計；小解(jie)決方案；降低成(cheng)本；無(wu)電(dian)(dian)(dian)磁干(gan)擾問題；適用于(yu)對小電(dian)(dian)(dian)池(chi)和(he)小于(yu)15.A充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)的(de)電(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)。

開關充電器：更(geng)(geng)高的(de)效率和功耗；更(geng)(geng)復雜的(de)設計；更(geng)(geng)多(duo)組件；成(cheng)本更(geng)(geng)高；開關噪聲可能需要(yao)更(geng)(geng)多(duo)的(de)布局考(kao)慮；適合大容量電池(chi)和快速充電。

選擇哪種充電(dian)器(qi)取決于那些因素對特定的(de)設計(ji)最重要。通常，由(you)于小(xiao)型解決方案(an)尺寸，簡單(dan)的(de)設計(ji)和(he)較(jiao)低的(de)成(cheng)本，小(xiao)型電(dian)池(chi)和(he)低充電(dian)電(dian)流應(ying)用，如可(ke)穿戴設備、物(wu)聯網等都(dou)優選線性充電(dian)器(qi)。智能手機、平板(ban)電(dian)腦和(he)筆(bi)記本電(dian)腦等高功率(lv)和(he)多單(dan)元電(dian)池(chi)應(ying)用將使用開關充電(dian)器(qi)。飛天鷹 電(dian)源適(shi)配(pei)器(qi)廠(chang)家(jia)17年專業(ye)研發生產電(dian)源適(shi)配(pei)器(qi)，歡迎前(qian)來咨詢。
