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
output current.
The LM828 operates at 12 kHz switching frequency to re-
duce output resistance and voltage ripple. With an operating
current of only 40 A (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.
