Product Summary

The LM2665M6X 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 LM2665M6X can also work as a voltage divider to split a voltage in the range of +1.8V to +11V in half. The LM2665M6X 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 LM2665M6X provides ideal performance for battery powered systems. The device is in SOT-23-6 package.
