LM2660/LM2661  
Switched Capacitor Voltage Converter  
General Description  
Features  
n Inverts or doubles input supply voltage  
n Narrow SO-8 and Mini SO-8 Package  
n 6.5typical output resistance  
The LM2660/LM2661 CMOS charge-pump voltage con-  
verter inverts a positive voltage in the range of 1.5V to 5.5V  
to the corresponding negative voltage. The LM2660/LM2661  
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/LM2661 provides ideal performance for battery  
powered systems. The LM2660/LM2661 may also be used  
as a positive voltage doubler.  
n 88% typical conversion efficiency at 100 mA  
n (LM2660) selectable oscillator frequency: 10 kHz/80 kHz  
n (LM2661) low current shutdown mode  
Applications  
n Laptop computers  
n Cellular phones  
The oscillator frequency can be lowered by adding an exter-  
nal capacitor to the OSC pin. Also, the OSC pin may be used  
to drive the LM2660/LM2661 with an external clock. For  
LM2660, a frequency control (FC) pin selects the oscillator  
frequency of 10 kHz or 80 kHz. For LM2661, an external  
shutdown (SD) pin replaces the FC pin. The SD pin can be  
used to disable the device and reduce the quiescent current  
to 0.5 µA. The oscillator frequency for the LM2661 is 80 kHz.
