Micropower Regulated 3.3V/5V Charge Pump


Posted on Feb 6, 2014

The LTC1754 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 VIN and VOUT) make the LTC1754 ideally suited for sma

ll, 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 switched capacitor voltage doubler to produce a regulated output. It has thermal shutdown capability and can survive a continuous short circuit from VOUT to GND. The LTC1754 is available in a 6-pin SOT-23 package. * The USA list pricing shown is for BUDGETARY USE ONLY, shown in United States dollars (FOB USA per unit for the stated volume), and is subject to change.
