LM2665 Switched Capacitor Voltage Converter

Check for Samples: LM2665

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.
