6-Pin SOT-23 Package
The LTC ? 1754 is a micropower charge pump DC/DC
converter that produces a regulated output. The input
voltage range is 2V to 4.4V for 3.3V output and 2.7V to
5.5V for 5V output. Extremely low operating current and a
low external parts count (one flying capacitor and two
small bypass capacitors at V IN and V OUT ) make the LTC1754
ideally suited for small, battery-powered applications. The
total component area of the application circuit shown
below is only 0.052 inch 2 .
The LTC1754 operates as a Burst Mode TM switched capaci-
tor voltage doubler to produce a regulated output. It has
thermal shutdown capability and can survive a continuous
