AME7700/AME7701/AME7702
n General Description
n Features
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 required, however, in some cases, a single capacitor is
acceptable. Minimum capacitance is obtained with the
AME7701, while the AME7700 offers the lowest standby 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.
