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.

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.
