Description

General part information

LM2765 Series

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.
