1 / 9 page LM2765 Switched Capacitor Voltage Converter General Description 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. 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.
