LM2767

Switched Capacitor Voltage Converter

General Description

Features

n Doubles Input Supply Voltage

n SOT23-5 Package

The LM2767 CMOS charge-pump voltage converter oper-

ates 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.

n 20Ω Typical Output Impedance

n 96 Typical Conversion Efficiency at 15mA

The LM2767 operates at 11 kHz switching frequency to

avoid audio voice-band interference. With an operating cur-

most loads), the LM2767 provides ideal performance for bat-

tery powered systems. The device is manufactured in a

SOT23-5 package.
