Overview
Analog Microelectronics, Inc.
AME7700/AME7701/AME7702 nary i m i l Pre Switched Capacitor Voltage Doublers n 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 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 voltag...
