Additional Details

The LTC1517-5 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 6µA with no load) and low external parts count (one 0.1µF 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 0.045in².

The part operates as a Burst Mode^™ switched-capacitor voltage doubler to produce a regulated output. The part has thermal shutdown capability and can survive a continuous short circuit from V_OUT to GND. The device is available in a 5-pin SOT-23 package.

Applications

Cellular Telephones
Battery-Operated Equipment
Local Power Supplies
Handheld Instruments
PCMCIA Supplies
