125mA、频率可选、开关电容电压变换器

MAX1680/MAX1681无电感开关电容电压转换器可将+2.0V输入电压反相至+5.5V或将输入电压翻倍，同时提供高达125mA的输出电流。它们具有可选频率选项，支持使用小电容：4.7µF (MAX1680)、1µF (MAX1681)。这些电荷泵器件具有高输出电流能力，非常适合替代基于电感的稳压器，后者需要更昂贵的外部元件和额外的电路板空间。\n\n 这些器件的等效输出电阻（典型值为3.5Ω）使其能够提供高达125mA的电流，而压降仅为440mV。关断功能可将静态电流降至1µA以下。MAX1680/MAX1681采用8引脚SO封装。对于以更小的µMAX®封装提供高达50mA电流 • 可选开关频率：\n• 125kHz/250kHz (MAX1680)\n\n• 500kHz/1MHz (MAX1681)\n\n\n\n\n• 支持使用小电容（MAX1681为1µF）\n\n• 输出电流：125mA\n\n• 3.5Ω输出阻抗\n\n• 逻辑控制关断电流：1µA\n\n• 可配置为电压反相器或倍压器\n\n• 输入电压范围：+2.0V至+5.5V\n\n• 采用8引脚SO封装\n\n• 效率为90%;
