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