FEATURES  
DESCRIPTION  
The LM2665 CMOS charge-pump voltage converter  
operates as a voltage doubler for an input voltage in  
the range of +2.5V to +5.5V. Two low cost capacitors  
and a diode (needed during start-up) are used in this  
circuit to provide up to 40 mA of output current. The  
LM2665 can also work as a voltage divider to split a  
voltage in the range of +1.8V to +11V in half.

Doubles or Splits Input Supply Voltage  
6-Pin SOT-23 Package  
12Ω Typical Output Impedance  
90% Typical Conversion Efficiency at 40 mA  
1µA Typical Shutdown Current  
The LM2665 operates at 160 kHz oscillator frequency  
to reduce output resistance and voltage ripple. With  
an operating current of only 650 µA (operating  
efficiency greater than 90% with most loads) and 1µA  
typical shutdown current, the LM2665 provides ideal  
performance for battery powered systems. The  
device is in a SOT-23 package.
