General Description
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 A 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.
