1-µA Typical Shutdown Current 2 Applications • Cellular Phones • Pagers • PDAs • Operational Amplifier Power Supplies • Interface Power Supplies • Handheld Instruments 3 Description The LM2766 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 LM2766 operates at 200-kHz switching frequency to reduce output resistance and voltage ripple.
With an operating current of only 350 µA (operating efficiency greater than 90% with most loads) and 0.
1-µA typical shutdown current, the LM2766 provi...
