LM2767 Datasheet Switched Capacitor Voltage Converter

Manufacturer: Texas Instruments

General Description

The LM2767 CMOS charge-pump voltage converter operates as a voltage doubler for an input voltage in the range of 1.8 V to 5.5 V.

Two low-cost capacitors and a diode are used in this circuit to provide at least 15 mA of output current.

The LM2767 operates at 11-kHz switching frequency to avoid audio voice-band interference.
