MicroPower™ Regulated Charge Pump

™

ChargePump

General Description

Features

The AAT3110 ChargePump™ is a MicroPower

switched-capacitor voltage converter that delivers

a regulated output. No external inductor is required

for operation. Using three small capacitors, the

AAT3110 can deliver up to 150mA to the voltage

regulated output. The AAT3110 features very low

quiescent current and high efficiency over a large

portion of its load range making this device ideal

for battery-powered applications. Furthermore, the

combination of few external components and small

package size keeps the total converter board area

to a minimum in space restricted applications. The

AAT3110 operates in an output-regulated voltage

doubling mode. The regulator uses a pulse-skip-

ping technique to provide a regulated output from a

varying input supply. The AAT3110 contains a ther-

mal management circuit to protect the device

under continuous output short circuit conditions.
