General Description
The AME7700 series of economical, Charge-Pump Con-
verters efficiently double a +1.5V to +5.5V input to +3.0V
to +11V, with a working current exceeding 100mA. Due
to their simplicity, small size, and performance, these
CMOS converters have numerous applications.
For most cases, only (2) external capacitors are re-
quired, however, in some cases, a single capacitor is
acceptable. Minimum capacitance is obtained with the
AME7701, while the AME7700 offers the lowest stand-
by current. The AME7702 has a Frequency-Select pin
for added flexibility. The input voltage can be tripled or
quadrupled by cascading 2 Charge-Pumps. A single al-
kaline battery with it’s low start-up voltage, a single alka-
line battery can be configured with (2) AME7700’s to
quadruple the voltage and produce 5V out. Alternately,
with a 5V source, (2) AME7700’s can be configured to
triple the voltage and produce 15V out.
