LM2765 Datasheet Switched Capacitor Voltage Converter

Manufacturer: National Semiconductor (now Texas Instruments)

General Description

The LM2765 CMOS charge-pump voltage converter operates 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.

The LM2765 operates at 50 kHz switching frequency to reduce output resistance and voltage ripple.
