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.
With an operating current of only 40 µA (operating efficiency greater than 90% with most loads),
the LM2767 provides ideal performance for battery-powered systems. The device is manufactured in a
