LM2765 - Switched Capacitor Voltage Converter
The LM2765's CMOS charge pump voltage converter operates as a voltage doubler over the input voltage range of +1.8 V to +5.5 V. Two low-cost capacitors and diodes are used in this circuit to provide up to 20 mA of output current. The LM2765 operates at a switching frequency of 50 kHz to reduce output resistance and voltage ripple. With an operating current of only 130µA (operating efficiency greater than 90% with most loads) and a typical shutdown current of 0.1µA, the LM2765 provides ideal performance for power battery systems. Production equipment in SOT-23-6 package.
