Dual-Output Charge Pump with Shutdown

General Description The MAX864 CMOS, charge-pump, DC-DC voltage converter produces a positive and a negative output from a single positive input, and requires only four capacitors. The charge pump first doubles the input voltage, then inverts the doubled voltage. The input voltage ranges from +1.

雙輸出電荷泵，帶有關斷

MAX864 CMOS、電荷泵、DC-DC電壓轉換器從單個正輸入產生正負輸出，并且僅需四個電容。電荷泵首先將輸入電壓翻倍，然后將翻倍的電壓反相。輸入電壓范圍為+1.75V至+6.0V。\n\n 內部振蕩器的引腳可編程范圍為7kHz至185kHz，從而有助于優(yōu)化靜態(tài)電流、電容尺寸和開關頻率。55Ω輸出阻抗支持高達20mA的有用輸出電流。MAX864還具有1μA邏輯控制關斷功能。\n\n MAX864采用16引腳QSOP封裝，電路板面積與標準8引腳SOIC封裝相同。對于對空間更敏感的應用，MAX865采用8引腳μMAX?封裝，占用的電路板面積僅為MAX864的一半。\n\n ? 僅需四個電容\n\n? 雙路輸出（正負）\n\n? 低輸入電壓：+1.75V至+6.0V\n\n? 邏輯控制關斷電流：1μA\n\n? 可選頻率有助于優(yōu)化電容尺寸和電源電流;
