LM2664
Switched Capacitor Voltage Converter
General Description
The LM2664 CMOS charge-pump voltage converter inverts
a positive voltage in the range of +1.8V to +5.5V to the cor-
responding negative voltage of 1.8V to 5.5V. The LM2664
uses two low cost capacitors to provide up to 40 mA of out-
put current.
The LM2664 operates at 160 kHz oscillator frequency to re-
duce 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.
