3 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. 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 5-pin
SOT-23 package.
