Description
AI
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 VINand VOUT) 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 VOUTto GND. The device is available in a 5-pin SOT-23 package.ApplicationsCellular TelephonesBattery-Operated EquipmentLocal Power SuppliesHandheld InstrumentsPCMCIA Supplies
