The LTC1754ES6-5#TRMPBF is a 5V micropower regulated Charge Pump with shutdown that produces a regulated output. The input voltage range is 2.7 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 small, battery-powered applications. The total component area of the application circuit shown below is only 0.052 inch2. 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 efficiency of the LTC1754 is similar to that of a linear regulator with an effective input voltage of twice the actual input voltage.
