LM2665 Datasheet (National Semiconductor) - Switched Capacitor Voltage Converter

LM2665, Switched Capacitor Voltage Converter

The LM2665 CMOS charge-pump voltage converter operates as a voltage doubler for an input voltage in the range of +2.5V to +5.5V.

Two low cost capacitors and a diode (needed during start-up) are used in this circuit to provide up to 40 mA of output current.

The LM2665 can also work as a voltage divid
