LM2664

Switched Capacitor Voltage Converter

General Description

Features

n Inverts Input Supply Voltage

n SOT23-6 Package

The LM2664 CMOS charge-pump voltage converter inverts

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

corresponding negative voltage of −1.8V to −5.5V. The

LM2664 uses two low cost capacitors to provide up to 40 mA

of output current.

n 12Ω Typical Output Impedance

n 91% Typical Conversion Efficiency at 40 mA

n 1µA Typical Shutdown Current

The LM2664 operates at 160 kHz oscillator frequency to

reduce output resistance and voltage ripple. With an operat-

ing 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. The device is in SOT-23-6 package.
