FEATURES  
DESCRIPTION  
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 converters.  
With an operating current of only 300 μA and  
operating efficiency greater than 90% at most loads,  
the LM2662/LM2663 provides ideal performance for  
battery powered systems. The LM2662/LM2663 may  
also be used as a positive voltage doubler.

Laptop computers  
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.
