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