DESCRIPTION  
The CAT660 is a charge-pump voltage converter. It will  
inverta1.5Vto5.5Vinputtoa-1.5Vto-5.5Voutput.Only  
two external capacitors are needed. With a guaranteed  
100mAoutputcurrentcapability,theCAT660canreplace  
a switching regulator and its inductor. Lower EMI is  
achieved due to the absence of an inductor.  
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 SOIC packages are available in the  
industrial temperature range. The TDFN package has a  
4x4mmfootprintandfeaturesa0.8mmmaximumheight.  
Comparedtothe8-pinSOICtheTDFNpackagefootprint  
is nearly 50% less. For die availability, contact Catalyst  
Semiconductor marketing.  
In addition, the CAT660 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 voltage.  
A Frequency Control pin (BOOST/FC) is provided to  
select either a high (80kHz) or low (10kHz) internal  
oscillator frequency, thus allowing quiescent current vs.  
capacitor size trade-offs to be made. The 80kHz  
frequency is selected when the FC pin is connected to  
The CAT660 replaces the MAX660 and the LTC660.  
In addition, the CAT660 is pin compatible with the 7660/  
1044, offering an easy upgrade for applications with  
100mA loads.
