FEATURES  
DESCRIPTION  
The LM2660 CMOS charge-pump voltage converter  
is a versatile unregulated switched capacitor inverter  
or doubler. Operating from a wide 1.5V to 5.5V  
supply voltage, the LM2660 uses two low-cost  
capacitors to provide 100 mA of output current  
without the cost, size and EMI related to inductor-  
based converters. With an operating current of only  
120 µA and operating efficiency greater than 90% at  
most loads, the LM2660 provides ideal performance  
for battery-powered systems. LM2660 devices can be  
operated directly in parallel to lower output  
impedance, thus providing more current at a given  
voltage.

The FC (frequency control) pin selects between a  
nominal 10 kHz or 80 kHz oscillator frequency. The  
oscillator frequency can be lowered by adding an  
external capacitor to the OSC pin. Also, the OSC pin  
may be used to drive the LM2660 with an external  
clock up to 150 kHz. Through these methods, output  
ripple frequency and harmonics may be controlled.

Handheld Instruments  
Additionally, the LM2660 may be configured to divide  
a positive input voltage precisely in half. In this mode,  
input voltages as high as 11V may be used.
