FEATURES  
DESCRIPTION  
The LM2781 is a charge pump that inverts an input  
2
•
•
Inverts Input Voltage  
voltage in the range of 1.8V to 5.5V to the  
corresponding output voltage of -1.8V to -5.5V. With  
use of three or four low-cost external ceramic  
capacitors, the LM2781 can provide up to 50mA of  
output current.  
Ultra-Low Voltage Ripple and 8Ω Typical  
Output Resistance with Two Flying Capacitors  
•
Output Resistance of 18Ω Using One Flying  
Capacitor  
•
•
210kHz (typ.) Switching Frequency  
The LM2781 operates at a 210kHz typical switching  
frequency to minimize supply current (0.7mA typ.).  
Two charge pumps operate 180° out of phase to  
significantly reduce the output voltage ripple  
compared to that of traditional single-phase charge  
pump circuits. If larger output ripple can be tolerated,  
optional capacitor C2 may be omitted to reduce the  
cost and size of the solution. The LM2781 is available  
in an 8-pin DSBGA chip-scale package.
