50mA、頻率可選的開關(guān)電容電壓變換器

MAX860/MAX861電荷泵電壓轉(zhuǎn)換器用于將+1.5V至+5.5V范圍內(nèi)的輸入電壓反相，或?qū)?2.5V至+5.5V范圍內(nèi)的輸入電壓翻倍。由于開關(guān)頻率高，這些器件僅使用兩個(gè)小型低成本電容。其輸出為50mA，因此無需開關(guān)穩(wěn)壓器，也無需考慮電感及其相關(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200μA (MAX860)，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。 \n\n 頻率控制(FC)引腳提供三種開關(guān)頻率，以優(yōu)化電容尺寸和靜態(tài)電流，并防止干擾敏感電路。每個(gè)器件都有專門的一組可用頻率，每組三個(gè)。關(guān)斷（低電平有效SHDN） ? 8引腳、1.11mm高的μMAX封裝\n\n? 將輸入電源電壓反相或翻倍\n\n? 三個(gè)可選開關(guān)頻率\n\n? 高頻有助于減小電容尺寸\n\n? 50mA時(shí)效率為87%\n\n? 靜態(tài)電流：200μA (MAX860)\n\n? 關(guān)斷電源電流：1μA\n\n? 50mA負(fù)載時(shí)的壓降為600mV\n\n? 12Ω輸出電阻;
