AME7701 - Analog Microelectronics

AME7701 Switched Capacitor Voltage Doublers

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 capacit.
