描述 Description

General Description
The AAT3110 ChargePump is a member of AnalogicTechs Total Power Management IC™ (TPMIC™) product family. It 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 100mA 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 skipping technique to provide a regulated output from a varying input supply. The AAT3110 contains a thermal management circuit to protect the device under continuous output short-circuit conditions.
