General Description

The LTC®1517-3.3 is a micropower charge pump DC/DC converter that produces a regulated 3.3V output.

The input voltage range is 2V to 4.4V, allowing a single cell lithium battery to produce a regulated 3.3V output over the entire life of the battery.

Extremely low operating current (typically 6µA with no load) and low external parts count (one 0.1µF flying capacitor and two small bypass capacitors at VIN and VOUT) make the part ideally suited for small, light load batterypowered applications.
