LM2765

Switched Capacitor Voltage Converter

General Description

Features

n Doubles Input Supply Voltage

n SOT23-6 Package

The LM2765 CMOS charge-pump voltage converter oper-

ates 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 up to 20 mA of output current.

n 20Ω Typical Output Impedance

n 90% Typical Conversion Efficiency at 20 mA

n 0.1µA Typical Shutdown Current

The LM2765 operates at 50 kHz switching frequency to re-

duce output resistance and voltage ripple. With an operating

current of only 130 µA (operating efficiency greater than 90%

with most loads) and 0.1µA typical shutdown current, the

LM2765 provides ideal performance for battery powered

systems. The device is manufactured in a SOT-23-6 pack-

age.
