LM2682 Switched Capacitor Voltage Doubling Inverter

November 1999

LM2682

Switched Capacitor Voltage Doubling Inverter

General Description

The LM2682 is a CMOS charge-pump voltage inverter ca-

pable of converting positive voltage in the range of +2.0V to

+5.5V to the corresponding doubled negative voltage of

鈭?.0V to 鈭?1.0V 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 碌A(chǔ) and an operating ef-

ficiency greater than 90% with most loads, the LM2682 pro-

vides ideal performance for battery powered systems. The

LM2682 offers a switching frequency of 6 kHz.
