General Description
The AME7700 series of economical, Charge-Pump
Converters 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
alkaline battery
With it's low start-up voltage, a single alkaline 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.
