Overview

LM2767 Switched Capacitor Voltage Converter February 2000 LM2767 Switched Capacitor Voltage Converter 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 n n n n Doubles Input Supply...
