The AAT3112 is a member of AnalogicTech’s Total Power Management IC™ (TPMIC™) family. It is a dual voltage doubling charge pump that provides a regulated output voltage. It operates with an input voltage range of 2.7 to 5.0 volts. The device can deliver a constant 200mA output load current and up to 500mA of pulsed current. The 500mA peak current capability of the AAT3112 makes it ideal for white LED flash applications. A low external parts count (two 1µF flying capacitors and two small capacitors at V IN and V OUT ) makes the AAT3112 ideally suited for small battery-powered applications. The AAT3112 has a thermal management system to protect the device in the event of a short-circuit condition at the output pin. Built-in soft-start circuitry prevents excessive inrush current during start-up. A high charge pump switching frequency enables the use of very small external capacitors. A low current shutdown feature disconnects the load from V IN and reduces quiescent current to less than 1μA. The AAT3112 is available in a Pb-free 16-pin 3x3mm QFN package and is rated over the -40°C to +85°C temperature range.
