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.
The LM2664 operates at 160 kHz oscillator frequency to reduce output resistance and
voltage ripple. With an operating current of only 220 A (operating efficiency greater than
91% with most loads) and 1 A typical shutdown current, the LM2664 provides ideal
performance for battery powered systems. The device is in SOT-23-6 package.
