線性充(chong)(chong)(chong)電器(qi)和開關充(chong)(chong)(chong)電器(qi)廣泛應(ying)(ying)用(yong)(yong)于多種應(ying)(ying)用(yong)(yong)：助聽器(qi)、智能手表、傳感器(qi)節點、手機(ji)、筆記本電腦...數不勝數！每(mei)當使用(yong)(yong)可充(chong)(chong)(chong)電電池時，都需要一個充(chong)(chong)(chong)電器(qi)。然(ran)而，考慮到可用(yong)(yong)的(de)不同充(chong)(chong)(chong)電拓撲相關的(de)利(li)弊，您在選擇(ze)充電器時(shi)可能(neng)需要考慮(lv)更多因(yin)素。
兩種方(fang)法都有(you)其(qi)利(li)弊。線(xian)性(xing)(xing)充(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)體積小、易于使用、成本低廉。不用任(ren)何切換，它們即可適(shi)用于噪聲敏(min)感(gan)(gan)的應(ying)用；但是(shi)當充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)大時，功(gong)耗很高。開關充(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)以(yi)其(qi)高效(xiao)率而聞(wen)名，并可在輸入適(shi)配器(qi)(qi)(qi)(qi)電(dian)(dian)(dian)壓(ya)的廣(guang)泛變量下最小化功(gong)耗。但與線(xian)性(xing)(xing)充(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)相比，附加(jia)電(dian)(dian)(dian)感(gan)(gan)器(qi)(qi)(qi)(qi)和(he)電(dian)(dian)(dian)容器(qi)(qi)(qi)(qi)消(xiao)耗更多的電(dian)(dian)(dian)路板(ban)空間(jian)，增加(jia)了BOM成本和(he)設(she)計復雜性(xing)(xing)。
開關充電器功耗大，充電電流大；更高的效率和更低的功耗；簡單設計；小解決方案尺寸(cun)；
更復雜(za)的設計(ji)；降(jiang)低成本；更多組件；成本更高；無電磁干擾（EMI）問題。
開關噪聲可(ke)能需要更多的布(bu)局考(kao)慮，適用于對小電(dian)(dian)池(chi)(chi)(chi)或<1.5A充(chong)(chong)電(dian)(dian)電(dian)(dian)流的電(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)，適合(he)大容量(liang)電(dian)(dian)池(chi)(chi)(chi)和快(kuai)速充(chong)(chong)電(dian)(dian)
選擇(ze)哪(na)種充(chong)電(dian)(dian)(dian)(dian)器(qi)將取決(jue)于哪(na)些(xie)因素對于特(te)定設(she)計最重要(yao)。通(tong)常，由于小型(xing)(xing)解決(jue)方案尺寸，簡(jian)單的設(she)計和較低(di)的成本，小型(xing)(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)和低(di)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流應用(yong)，如可穿戴(dai)設(she)備(bei)、物聯網等(deng)都(dou)優選線性(xing)充(chong)電(dian)(dian)(dian)(dian)器(qi)。一些(xie)備(bei)用(yong)電(dian)(dian)(dian)(dian)池(chi)(chi)應用(yong)，如緊(jin)急呼叫(jiao)和汽車GPS定位(wei)跟(gen)蹤(zong)器(qi)也(ye)更(geng)優選線性(xing)充(chong)電(dian)(dian)(dian)(dian)器(qi)。智能手機、平板(ban)電(dian)(dian)(dian)(dian)腦和筆記本電(dian)(dian)(dian)(dian)腦等(deng)高功率(lv)和多(duo)單元電(dian)(dian)(dian)(dian)池(chi)(chi)應用(yong)將使(shi)用(yong)開關充(chong)電(dian)(dian)(dian)(dian)器(qi)
