CMOS Switched-Capacitor Voltage Converters

GENERAL DESCRIPTION The ADM660/ADM8660 is a charge-pump voltage converter that can be used to either invert the input supply voltage giving VOUT = –VIN or double it (ADM660 only) giving VOUT = 2
VIN. Input voltages ranging from +1.5 V to +7 V can be inverted into a negative –1.5 V to –7 V o

具有低功耗关断引脚的CMOS开关电容电压转换器

ADM660/ADM8660是一款电荷泵电压转换器，可用来将输入电源电压反相，使VOUT = -VIN 或将它加倍（仅限ADM660），使VOUT = 2 x VIN。 +1.5 V至+7 V范围内的输入电压可以反相为-1.5 V至-7 V输出电压。这种反相方案适合在单电源系统中产生负供电轨。电荷泵只需用两个较小的外部电容。50 mA以下输出电流可以实现90%以上的功效，100 mA输出电流则可以实现80%以上的功效。 利用频率控制(FC)输入引脚，可选择25 kHz或120 kHz的电荷泵工作频率，以便优化电容大小和静态电流。选择25 kHz时，适合用10 µF外部 • ADM660: 使输入电源电压反相或加倍\n\n• ADM8660: 使输入电源电压反相\n\n• 输出电流：100 mA\n\n• 关断功能(ADM8660)\n\n• 2.2 µF或10 µF电容;
