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 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.
