假設所設想的電路請求電源有下的樂音戰紋波抑制，請求占用PCB板里積小（如腳機等腳持電子產物），電路電源沒有容許利用電感器（如腳機），nxp電源管理芯片需(xu)求(qiu)具有(you)瞬時校準戰輸出(chu)形態自檢功用(yong)，請求(qiu)穩壓器壓降及本身功耗低,線路成本低且計劃儉樸，那末線性電源是最得當的挑選。

這(zhe)類電(dian)(dian)(dian)(dian)源(yuan)包羅以下的(de)(de)手(shou)藝：nxp電(dian)(dian)(dian)(dian)源(yuan)管(guan)理(li)(li)芯(xin)片的(de)(de)精(jing)細電(dian)(dian)(dian)(dian)壓取(qu)根本表示，下性(xing)能、低樂音的(de)(de)運放(fang)，高壓降調解(jie)管(guan)，低靜態電(dian)(dian)(dian)(dian)流。nxp電(dian)(dian)(dian)(dian)源(yuan)管(guan)理(li)(li)芯(xin)片正在(zai)小(xiao)功率供電(dian)(dian)(dian)(dian)、運放(fang)背電(dian)(dian)(dian)(dian)源(yuan)、LCD/LED驅動等場(chang)所，常使用基于電(dian)(dian)(dian)(dian)容的(de)(de)開閉電(dian)(dian)(dian)(dian)源(yuan)芯(xin)片，也便是(shi)凡是(shi)所道(dao)的(de)(de)電(dian)(dian)(dian)(dian)荷(he)泵(beng)。基于電(dian)(dian)(dian)(dian)荷(he)泵(beng)事情道(dao)理(li)(li)的(de)(de)芯(xin)片產物(wu)很多(duo)，比如那是(shi)一種由低噪聲、恒定(ding)頻次的(de)(de)電(dian)(dian)(dian)(dian)荷(he)轉換器(qi)組成的(de)(de)黑光(guang)LED驅動芯(xin)片。
