LM828, Switched Capacitor Voltage Converter
The LM828 CMOS charge-pump voltage converter inverts a positive voltage in the range of +1.8V to +5.5V to the corresponding 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 freq
