稳压型、可调节、-2倍压反相电荷泵

MAX868反相电荷泵提供了一种低成本、紧凑的解决方案，用于从1.8V至5.5V的正输入电压产生高达-2 x VIN的调节负电压。它使用脉冲频率调制(PFM)控制方案来产生调节后的负输出电压。PFM操作的实现方式是根据需要控制内部450kHz振荡器的开关，以维持输出电压调节。这种专门设计的按需开关方案为MAX868提供了出色的轻载效率，而且不会降低其满载工作效率（高达30mA），可以借助较小的电容来利用振荡器的高开关频率。\n\n MAX868无需电感；仅需四个电容即可构建一个完整的DC-DC转换器。只需添加两个电阻即可实现输出电压调节。MAX868采用10引脚µMAX®封装，高度仅 • 稳压负输出电压（高达-2 x VIN）\n\n• 超小型10引脚µMAX封装\n\n• 按需开关频率高达450kHz\n\n• 静态电源电流：30µA\n\n• 仅需四个小型外部电容\n\n• 输入电压范围：1.8V至5.5V\n\n• 逻辑控制关断电流：0.1µA\n\n• 高达30mA输出电流\n\n• 可调输出电压;
