简  介:MicroPower Regulated Charge Pump General Description The AAT3111 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 AAT3111 can deliver up to 150mA to the voltage regulated output. The AAT3111 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 AAT3111 operates in an output-regulated voltage doubling mode. The regulator uses a pulseskipping technique to provide a regulated output from a varying input supply. The AAT3111 contains a thermal management circuit to protect the device under continuous output short-circuit conditions. The AAT3111 is available in a Pb-free, surfacemount 6-pin SOT23 or 8-pin SC70JW package and is rated over the -40°C to +85°C temperature range.
