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 provides ideal performance for battery-
powered systems. The device is manufactured in a
SOT-23 6-pin package.
