  • Doubles Input Supply Voltage
  • SOT-23 6-Pin Package
  • 20-Ω Typical Output Impedance
  • 90% Typical Conversion Efficiency at 20 mA
  • 0.1-μA Typical Shutdown Current
  • Doubles Input Supply Voltage
  • SOT-23 6-Pin Package
  • 20-Ω Typical Output Impedance
  • 90% Typical Conversion Efficiency at 20 mA
  • 0.1-μA Typical Shutdown Current

The LM2765 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.

The LM2765 operates at 50-kHz switching frequency to reduce output resistance and voltage ripple. With an operating current of only 130 µA (operating efficiency greater than 90% with most loads) and 0.1-µA typical shutdown current, the LM2765 provides ideal performance for battery powered systems. The device is manufactured in a 6-pin SOT-23 package.

For all available packages, see the orderable addendum at the end of the data sheet.
