General Description

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 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 SOT23-5 package.

Features

  • Doubles Input Supply Voltage
  • SOT23-5 Package
  • 20 Typical Output Impedance
  • 96% Typical Conversion Efficiency at 15mA

Applications

  • Cellular Phones
