MAX774 | -5V/-12V/-15V or Adjustable, High-Efficiency, Low IQ Inverting DC-DC Controllers General Description The MAX774/MAX775/MAX776 inverting switching regulators deliver high efficiency over three decades of load current. A unique current-limited, pulse-frequency-modulated (PFM) control scheme provides the benefits of pulse-width modulation (high efficiency with heavy loads), whil 文件:163.07 Kbytes 頁數(shù):16 Pages | MAXIM 美信 | MAXIM | |
MAX774 | -5V/-12V/-15V或可調(diào)電壓、高效、低IQ反相DC-DC控制器 MAX774/MAX775/MAX776反相開關(guān)穩(wěn)壓器在負(fù)載電流的三個數(shù)量級范圍內(nèi)提供高效率。專門設(shè)計(jì)的限流、脈沖頻率調(diào)制(PFM)控制方案提供了脈沖寬度調(diào)制的優(yōu)勢(重負(fù)載時效率高),同時使用的電源電流小于100μA(PWM轉(zhuǎn)換器的電源電流為2mA至10mA)。因此它們在寬負(fù)載范圍內(nèi)具有高效率。\n\n 這些IC還使用小型外部元件;高開關(guān)頻率(高達(dá)300kHz)允許其使用直徑小于5mm的表面貼裝磁性元件。\n\n MAX774/MAX775/MAX776的輸入電壓范圍為3V至16.5V,預(yù)設(shè)輸出電壓分別為-5V、-12V和-15V。用戶也可使用兩個電阻調(diào)節(jié)輸出電壓。最大VI ? 對于5mA至1A負(fù)載電流,效率達(dá)85%\n\n? 輸出功率:最高5W\n\n? 電源電流:100μA(最大值)\n\n? 關(guān)斷電流:5μA(最大值)\n\n? 輸入范圍:3V至16.5V\n\n? -5V (MAX774)、-12V (MAX775)、-15V (MAX776)或可調(diào)輸出電壓\n\n? 限流PFM控制方案\n\n? 開關(guān)頻率:300kHz; | ADI 亞德諾 | ADI | |
