LM2767 - Switched Capacitor Voltage Converter

Datasheet Summary

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.

Features

  • 1 Doubles Input Supply Voltage.
  • SOT-23 5-Pin Package.
  • 20-Ω Typical Output Impedance.
  • 96% Typical Conversion Efficiency at 15 mA 2.
