Torex主機電源的XC9244產品轉換成器不錯用到鑲入0.65ΩP銑面驅動包硫化鋅管和0.45ΩN一端旋轉開關結晶體管的減壓數據同步整流DC/DC改換器。只有的運用次級線圈和電解電容代替靜態零部件，應該安全保證400mA的谷值電壓。

XC9244產(chan)品(pin)系(xi)列變(bian)換(huan)器外部放置(zhi)打出電(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)流，大部分是0.8V～4.0V的(de)(de)范疇內(±2.以(yi)(yi)0.以(yi)(yi)05V的(de)(de)間(jian)(jian)隔挑輸出的(de)(de)電(dian)(dian)(dian)(dian)壓值。XC9244系(xi)例互(hu)轉器的(de)(de)按鈕開關聲音頻率高(gao)至1.2MHz也可以(yi)(yi)應該(gai)削減間(jian)(jian)接集成電(dian)(dian)(dian)(dian)路芯(xin)片(pian)的(de)(de)要求。選擇使用(yong)USPN-6裝封。USPN-6封裝形(xing)式是最(zui)符合非常和室內空間(jian)(jian)問(wen)題的(de)(de)利用(yong)。

基于待機時(shi)全體成員電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)源線路停機在運轉，所(suo)以咧需求量電(dian)(dian)(dian)(dian)(dian)流(liu)量會(hui)控住(zhu)到1.0μA下(xia)面。待機時(shi)，由CL的(de)(de)速度蓄電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)效果(guo)性(xing)使能(neng)VOUT-VSS中間的(de)(de)內部管理開關(guan)按鈕導通(tong)，CL的(de)(de)帶(dai)電(dian)(dian)(dian)(dian)(dian)粒子經歷電(dian)(dian)(dian)(dian)(dian)壓(ya)表內阻(zu)擊穿。該功效與作用(yong)就能(neng)夠防止(zhi)出現待機時(shi)VOUT前因后果(guo)電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)誤區(qu)基本(ben)操作。內部結(jie)構將軟加載時(shi)候設有(you)成0.25ms（TYP.，能(neng)夠讓輸出額定電(dian)(dian)(dian)(dian)(dian)壓(ya)發展變高。

為愛(ai)護IC抗(kang)御熱損(sun)傷，XC9244全系列轉換(huan)成器在與會人員(yuan)確認(ren)格局下配備了直流電壓約束條件功能(neng)性。

XC9244一系(xi)列轉換成器嵌到(dao)UVLO(讀取欠(qian)壓鎖閉(bi)Under Voltage Lock Out)用途性(xing)，當鍵入端電壓不低于(yu)2.25V(最大的)當內外推動結晶體管強行(xing)終止(zhi)正(zheng)常的工作。
