CMOS單片電壓變換器

MAX660單片電荷泵電壓反相器將+1.5V至+5.5V輸入轉(zhuǎn)換為相應(yīng)的1.5V至-5.5V輸出。電荷泵僅使用兩個低成本電容，輸出電流為100mA，取代了開關(guān)穩(wěn)壓器，因此無需使用電感，也無需考慮相關(guān)成本、尺寸和EMI。在其大部分負(fù)載電流范圍內(nèi)，效率均高于90%，再加上典型工作電流僅為120μA，可以為電池供電和電路板級電壓轉(zhuǎn)換應(yīng)用提供出色的性能。MAX660還可以將輸入電源或電池的輸出電壓翻倍，在100mA下從+5V輸入提供+9.35V。\n\n 頻率控制(FC)引腳用于選擇10kHz典型值或80kHz典型值（最小值40kHz）操作以優(yōu)化電容尺寸和靜態(tài)電流。振蕩器頻率也可以通; ? 小型電容\n\n? 100mA負(fù)載時典型損耗為0.65V\n\n? 低工作電流：120μA\n\n? 輸出阻抗：6.5Ω（典型值）\n\n?
