SNVS069D – FEBRUARY 2000 – REVISED AUGUST 2015 LM2767 Switched Capacitor Voltage Converter
1 Features 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. 1 Doubles Input Supply Voltage
SOT-23 5-Pin Package
20-О© Typical Output Impedance
96% Typical Conversion Efficiency at 15 mA 2 Applications Cellular Phones
Pagers
PDAs, Organizers
Operational Amplifier Power Suppliers
Interface Power Suppliers
Handheld Instruments The LM2767 operates at 11-kHz switching frequency
to avoid audio voice-band interference. With an
operating current of only 40 ВµA (operating efficiency
greater than 90% with most loads), the LM2767 …
