LM2765

SNVS070D –MARCH 2000–REVISED SEPTEMBER 2016

LM2765 Switched-Capacitor Voltage Converter

1 Features

3 Description

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.

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 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.
