50mA、频率可选的开关电容电压变换器

MAX860/MAX861电荷泵电压转换器用于将+1.5V至+5.5V范围内的输入电压反相，或将+2.5V至+5.5V范围内的输入电压翻倍。由于开关频率高，这些器件仅使用两个小型低成本电容。其输出为50mA，因此无需开关稳压器，也无需考虑电感及其相关成本、尺寸和EMI。在其大部分负载电流范围内，效率均高于90%，再加上典型工作电流仅为200µA (MAX860)，可以为电池供电和电路板级电压转换应用提供出色的性能。\n\n 频率控制(FC)引脚提供三种开关频率，以优化电容尺寸和静态电流，并防止干扰敏感电路。每个器件都有专门的一组可用频率，每组三个。关断（低电平有效SHDN）引 • 8引脚、1.11mm高的µMAX封装\n\n• 将输入电源电压反相或翻倍\n\n• 三个可选开关频率\n\n• 高频有助于减小电容尺寸\n\n• 50mA时效率为87%\n\n• 静态电流：200µA (MAX860)\n\n• 关断电源电流：1µA\n\n• 50mA负载时的压降为600mV\n\n• 12Ω输出电阻;
