LM2682 Datasheet Switched Capacitor Voltage Doubling Inverter

Manufacturer: Texas Instruments

Overview: LM2682 www.ti.com SNVS044B – NOVEMBER 1999 – REVISED MAY 2013 LM2682 Switched Capacitor Voltage Doubling Inverter Check for Samples:.

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 μA and an operating efficiency greater than 90% with most loads, the LM2682 provides ideal performance for battery powered systems.
