AAT3112 | 500mA High Efficiency Charge Pump For White LED Flash Applications

The AAT3112 is a member of AnalogicTechs Power Management IC family. It is a dual Charge Pump voltage doubler that provides a regulated output voltage. Operating with an input voltage range of 2.7V to 5.0V, the device CAN deliver up to 500mA of pulsed current, making it ideal for white LED Flash applications. Low external parts counts (two 1F flying capacitors and two small capacitors at VIN and VOUT) make 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, and a low current shutdown feature disconnects the load from VIN and reduces quiescent current to less than 1A. The AAT3112 is available in a 16-pin 3x3mm QFN package.
