The LTC ? 1517-5 is a micropower charge pump DC/DC
converter that produces a regulated 5V output. The input
voltage range is 2.7V to 5V. Extremely low operating current
(typically 6 μ A with no load) and low external parts count (one
0.1 μ F flying capacitor and two small bypass capacitors at V IN
and V OUT ) make the part ideally suited for small, light load
battery-powered applications. The total printed circuit board
area of the application circuit shown below is only 0.045in 2 .
The part operates as a Burst Mode TM switched-capacitor
voltage doubler to produce a regulated output. The part has
thermal shutdown capability and can survive a continuous
