LM2767 Switched Capacitor Voltage Converter

Check for Samples: LM2767

FEATURES

DESCRIPTION

•

Doubles Input Supply Voltage

SOT-23 5-Pin Package

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.

20Ω Typical Output Impedance

96% Typical Conversion Efficiency at 15mA

APPLICATIONS

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 SOT-23 5-

pin package.
