LM2682 Datasheet (Texas Instruments) - Switched Capacitor Voltage Doubling Inverter

LM2682, Switched Capacitor Voltage Doubling Inverter

The LM2682 is a CMOS charge-pump voltage inverter capable of converting positive voltage in the range of +2.0V to +5.5V to the corresponding doubled negative voltage of *4.0V to *11.0V respectively.

The LM2682 uses three low cost capacitors to provide 10 mA of output current without
