LM2664 Datasheet (Texas Instruments) - Switched Capacitor Voltage Converter

LM2664, Switched Capacitor Voltage Converter

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 oscillat
