LM828  
Switched Capacitor Voltage Converter  
General Description  
Features  
n Inverts Input Supply Voltage  
n SOT-23-5 Package  
The LM828 CMOS charge-pump voltage converter inverts a  
positive voltage in the range of +1.8V to +5.5V to the corre-  
sponding negative voltage of −1.8V to −5.5V. The LM828  
uses two low cost capacitors to provide up to 25 mA of out-  
put current.  
n 20Typical Output Impedance  
n 97% Typical Conversion Efficiency at 5 mA  
The LM828 operates at 12 kHz switching frequency to re-  
duce output resistance and voltage ripple. With an operating  
current of only 40 µA (operating efficiency greater than 96%  
with most loads), the LM828 provides ideal performance for  
battery powered systems. The device is in a tiny SOT-23-5  
package.
