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
the cost, size, and EMI related to inductor based circuits.
With an operating current of only 150 μA and an operating
efficiency greater than 90% with most loads, the LM2682
provides ideal performance for battery powered systems.
The LM2682 offers a switching frequency of 6 kHz.
