High Frequency 100mA CMOS Charge Pump,  
Inverter/Doubler  
E TM  
R
FEATURES  
■ Converts V+ to V- or V+ to 2V+  
■ Low output resistance, 10Ω max.  
■ High power efficiency  
■ Pin-compatible to MAX660, LTC660 with higher  
frequency operation  
■ Available in 8-pin SOIC andDIP packages  
■ Lead-free, halogen-free package option  
■ Selectable charge pump frequency of 25kHz  
or 135kHz; optimize capacitor size.  
■ Low quiescent current  
APPLICATIONS  
■ Negative voltage generator  
■ Voltage doubler  
■ Low EMI power source  
■ Instrumentation  
■ GaAs FET biasing  
■ LCD contrast bias  
■ Cellular phones, pagers  
■ Voltage splitter  
■ Lithium battery power supply  
DESCRIPTION  
The CAT661 is a charge-pump voltage converter. It can  
invert a positive input voltage to a negative output. Only  
two external capacitors are needed. With a guaranteed  
100mAoutputcurrentcapability,theCAT661canreplace  
a switching regulator and its inductor. Lower EMI is  
achieved due to the absence of an inductor.  
connected to V+. The operating frequency can also be  
adjusted with an external capacitor at the OSC pin or by  
driving OSC with an external clock.  
Both 8-pin DIP and SO packages are available. For die  
availability, contact Catalyst Semiconductor marketing.  
The CAT661 can replace the MAX660 and the LTC660  
in applications where higher oscillator frequency and  
smaller capacitors are needed. In addition, the CAT661  
is pin compatible with the 7660/1044, offering an easy  
upgrade for applications with 100mA loads.  
In addition, the CAT661 can double a voltage supplied  
from a battery or power supply. Inputs from 2.5V to 5.5V  
will yield a doubled, 5V to 11V output.  
A Frequency Control pin (BOOST/FC) is provided to  
select either a high (typically 135kHz) or low (25kHz)  
internal oscillator frequency, thus allowing quiescent  
current vs. capacitor size trade-offs to be made. The  
135kHz frequency is selected when the FC pin is
