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.

双输出电荷泵，带有关断

MAX864 CMOS、电荷泵、DC-DC电压转换器从单个正输入产生正负输出，并且仅需四个电容。电荷泵首先将输入电压翻倍，然后将翻倍的电压反相。输入电压范围为+1.75V至+6.0V。\n\n 内部振荡器的引脚可编程范围为7kHz至185kHz，从而有助于优化静态电流、电容尺寸和开关频率。55Ω输出阻抗支持高达20mA的有用输出电流。MAX864还具有1µA逻辑控制关断功能。\n\n MAX864采用16引脚QSOP封装，电路板面积与标准8引脚SOIC封装相同。对于对空间更敏感的应用，MAX865采用8引脚µMAX®封装，占用的电路板面积仅为MAX864的一半。\n\n • 仅需四个电容\n\n• 双路输出（正负）\n\n• 低输入电压：+1.75V至+6.0V\n\n• 逻辑控制关断电流：1µA\n\n• 可选频率有助于优化电容尺寸和电源电流;
