LM2664
Switched Capacitor Voltage Converter
General DescriptionThe LM2664 CMOS charge-pump voltage converter inverts positive voltagein the rangeof +1.8Vto +5.5Vto the
corresponding negative voltageof −1.8Vto −5.5V. The
LM2664 uses two low cost capacitorsto provideupto40 mA output current.
The LM2664 operatesat 160 kHz oscillator frequencyto
reduce output resistance and voltage ripple. Withan operat-
ing currentof only 220µA (operating efficiency greater than
91% with most loads) and1 µAtypical shutdown current,the
LM2664 provides ideal performancefor battery powered
systems. The deviceisin SOT-23-6 package.
