LM2662/LM2663  
Switched Capacitor Voltage Converter  
General Description  
Features  
The LM2662/LM2663 CMOS charge-pump voltage converter  
inverts a positive voltage in the range of 1.5V to 5.5V to the  
corresponding negative voltage. The LM2662/LM2663 uses  
two low cost capacitors to provide 200 mA of output current  
without the cost, size, and EMI related to inductor based con-  
verters. With an operating current of only 300 μA and oper-  
ating efficiency greater than 90% at most loads, the LM2662/  
LM2663 provides ideal performance for battery powered sys-  
tems. The LM2662/LM2663 may also be used as a positive  
voltage doubler.  
Inverts or doubles input supply voltage  
Narrow SO-8 Package  
3.5Ω typical output resistance  
86% typical conversion efficiency at 200 mA  
(LM2662) selectable oscillator  
frequency: 20 kHz/150 kHz  
(LM2663) low current shutdown mode  
Applications  
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 LM2662/LM2663 with an external clock. For  
LM2662, a frequency control (FC) pin selects the oscillator  
frequency of 20 kHz or 150 kHz. For LM2663, 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 10 μA. The oscillator frequency for LM2663 is 150 kHz.
