雙路、高效率、PFM、升壓型DC-DC控制器

MAX863雙路輸出DC-DC轉(zhuǎn)換器采用緊湊的封裝，包含兩個(gè)獨(dú)立的升壓控制器。當(dāng)兩個(gè)控制器都打開時(shí)，這種單片Bi-CMOS設(shè)計(jì)僅消耗85μA。輸入范圍低至1.5V，允許用于組織整理工具、翻譯器和其他低功率手持產(chǎn)品。MAX863在20mA至1A以上的輸出負(fù)載下提供90%的效率。這種節(jié)省空間的器件采用16引腳QSOP封裝，與8引腳SOIC的面積相同。\n\n 該器件采用限流、脈沖頻率調(diào)制(PFM)控制架構(gòu)，可降低啟動(dòng)浪涌電流并保持低靜態(tài)電流，以實(shí)現(xiàn)出色的低電流效率。每個(gè)控制器驅(qū)動(dòng)一個(gè)低成本的外部N溝道MOSFET開關(guān)，其尺寸可以針對(duì)任何輸出電流或電壓進(jìn)行優(yōu)化。\n\n ? 超小的雙路升壓轉(zhuǎn)換器：16引腳QSOP\n\n? 90%效率\n\n? 1.5V啟動(dòng)電壓\n\n? 總靜態(tài)電源電流：85μA（最大值）\n\n? 關(guān)斷模式下為1μA\n\n? 獨(dú)立關(guān)斷輸入\n\n? 驅(qū)動(dòng)表面貼裝、雙N溝道MOSFET\n\n? 低電池輸入/輸出比較器\n\n? 升壓/降壓可配置;
