style="text-indent:25px">充電電源“性能”和“成本”是一對(duì)相愛相殺的冤家，讓多少工程師面臨兩難的選擇，多少辛辛苦苦做的方案，由于成本問題不得不放棄。是為了性能不顧成本？還是為了成本**性能？怎樣平衡性能和成本，這是在產(chǎn)品設(shè)計(jì)中亙古不變的話題。對(duì)于同樣輸入輸出電壓的DC/DC電源模塊來說，輸出功率和工作溫度范圍是影響其成本的主要因素。電子器件工作溫度范圍一般分為：商業(yè)級(jí)（0~70℃）、工業(yè)級(jí)（-40~85℃）、車規(guī)級(jí)（-40~105℃）、**級(jí)（-55~125℃）等。由于溫度等級(jí)不同，對(duì)材料和制造工藝的要求不同，模塊成本就相差很大了。如果在體積（封裝形式）一定的條件下實(shí)際使用功率已經(jīng)接近模塊額定功率，那么模塊標(biāo)稱的溫度范圍就必須嚴(yán)格滿足實(shí)際使用需求甚至略有余量。如果由于成本考慮選擇了較小溫度范圍的產(chǎn)品，實(shí)際使用溫度已經(jīng)逼近模塊極限溫度的情況，怎么辦呢？這時(shí)可以采用降額使用的辦法，即選擇功率或封裝更大一些的產(chǎn)品，這樣“大馬拉小車”，溫升低，能夠從一定程度上緩解這一矛盾。內(nèi)蒙古充電電源生產(chǎn)廠商只要一個(gè)電源模塊，配上少量分立元件，就可獲得電源。</p><div

style="text-indent:25px">充電電源模塊，工作頻率一般而言工作頻率越高，輸出紋波噪聲就更小，電源動(dòng)態(tài)響應(yīng)也更好，但是對(duì)元器件特別是磁性材料的要求也越高，成本會(huì) 有增加，所以國內(nèi)電源模塊產(chǎn)品開關(guān)頻率多為在
