LM2767
Switched Capacitor Voltage Converter
General Description
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 mAof output current.
The LM2767 operates at 11 kHz switching frequency to
avoid audio voice-band interference. With an operating cur-
rent of only 40 μA(operating efficiency greater than 90% with
most loads), the LM2767 provides ideal performance for bat-
tery powered systems. The device is manufactured in a
SOT23-5 package.
