  Description

(1.2MHz) switched capacitor voltage doubler. It produce a regulated output voltage from a 2.7V to 4.5V input with up to 250mA of output current. Low external parts count (one flying capacitor and two small bypass capacitors at VIN and small, battery-powered applications. A new charge-pump architecture maintains constant switching frequency to zero load and reduces both output and input ripple. The can survive a continuous short circuit from VOUT to GND. Builtin soft-start circuitry prevents excessive inrush current during start-up. High switching frequency enables the use of small ceramic capacitors. A low current shutdown feature disconnects the load from VIN and reduces quiescent current to <1uA
