Product Summary
The AAT3110IGU-4.5 ChargePump is a member of AnalogicTech Total Power Management IC (TPMI) 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 AAT3110IGU-4.5 can deliver up to 100mA to the voltage regulated output. The AAT3110IGU-4.5 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 AAT3110IGU-4.5 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 AAT3110IGU-4.5 contains a thermal management circuit to protect the device under continuous output short-circuit conditions.
