SNVS071C – MARCH 2000 – REVISED SEPTEMBER 2015 LM2766 Switched Capacitor Voltage Converter
1 Features 3 Description The LM2766 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 up to
20 mA of output current. 1 Doubles Input Supply Voltage
SOT-23 6-Pin Package
20-О© Typical Output Impedance
90% Typical Conversion Efficiency at 20 mA
0.1-ВµA Typical Shutdown Current 2 Applications Cellular Phones
Pagers
PDAs
Operational Amplifier Power Supplies
Interface Power Supplies
Handheld Instruments The LM2766 operates at 200-kHz switching
frequency to reduce output resistance and voltage
ripple. With an operating current of only 350 ВµA …
