LM828
Switched Capacitor Voltage Converter
General Description
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.
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.
