The ADM660 / ADM8660 is a charge-pump voltage converter that can be used to either invert the input supply voltage givingVOUT = -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 output supply. This inverting scheme is ideal for generating a negative rail in single power supply systems. Only two small external capacitors are needed for the charge pump. Output currents up to 50 mA with greater than 90% efficiency are achievable, while 100 mA achieves greater than 80% efficiency.A Frequency Control (FC) input pin is used to select either25 kHz or 120 kHz charge-pump operation. This is used to optimize capacitor size and quiescent current. With 25 kHz selected, a 10 µF external capacitor is suitable, while with 120 kHz the capacitor may be reduced to 2.2 µF. The oscillator frequency on the ADM660 can also be controlled with an external capacitor connected to the OSC input or by driving this input with an external clock. In
