T he ADM660/ADM8660 is a charge-pump voltage converter
that can be used to either invert the input supply voltage giving

or double it (ADM660 only) giving V

×
V
IN
.
Input voltages ranging from +1.5 V to +7 V can be inverted into
a negative –1.5 V to –7 V output supply. T his 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 either
25 kHz or 120 kHz charge-pump operation. T his is used to
optimize capacitor size and quiescent current. With 25 kHz
selected, a 10
μ
F external capacitor is suitable, while with
120 kHz the capacitor may be reduced to 2.2
μ
F. T he oscillator
frequency on the ADM660 can also be controlled with an exter-
nal capacitor connected to the OSC input or by driving this in-
put with an external clock. In applications where a higher supply
voltage is desired it is possible to use the ADM660 to double
the input voltage. With input voltages from 2.5 V to 7 V, output
voltages from 5 V to 14 V are achievable with up to 100 mA
output current.
T he ADM8660 features a low power shutdown (SD) pin in-
stead of the external oscillator (OSC) pin. T his can be used to
disable the device and reduce the quiescent current to 300 nA.
