LM2664

SNVS005E –NOVEMBER 1999–REVISED DECEMBER 2014

LM2664 Switched Capacitor Voltage Converter

1 Features

3 Description

The LM2664 CMOS charge-pump voltage converter

inverts a positive voltage in the range of 1.8 V to 5.5

V to the corresponding negative voltage of −1.8 V to

−5.5 V. The device uses two low-cost capacitors to

provide up to 40 mA of output current.

Inverts Input Supply Voltage

6-Pin SOT-23 Package

12-Ω Typical Output Impedance

91% Typical Conversion Efficiency at 40 mA

1-µA Typical Shutdown Current

The LM2664 operates at 160-kHz oscillator frequency

to reduce output resistance and voltage ripple. With

an operating current of only 220 µA (operating

efficiency greater than 91% with most loads) and 1-

µA typical shutdown current, the LM2664 provides

ideal performance for battery-powered systems.
