FEATURES  
DESCRIPTION  
The LTC®660 is a monolithic CMOS switched-capacitor  
voltage converter. It performs supply voltage conversion  
from positive to negative from an input range of 1.5V to  
5.5V, resulting in complementary output voltages of  
1.5V to 5.5V. It also performs a doubling at an input  
voltage range of 2.5V to 5.5V, resulting in a doubled  
output voltage of 5V to 11V. Only two external capacitors  
are needed for the charge pump and charge reservoir  
functions.  
Simple Conversion of 5V to 5V Supply  
Output Drive: 100mA  
ROUT: 6.5(0.65V Loss at 100mA)  
BOOST Pin (Pin 1) for Higher Switching Frequency  
Inverting and Doubling Modes  
Minimum Open Circuit Voltage Conversion  
Efficiency: 99%  
Typical Power Conversion Efficiency  
with a 100mA Load: 88%  
Easy to Use  
The converter has an internal oscillator that can be  
overdriven by an external clock or slowed down when  
connected to a capacitor. The oscillator runs at a 10kHz  
frequency when unloaded. A higher frequency outside the  
audio band can also be obtained if the BOOST pin is tied  
to V+.
