500mA High Efficiency Charge Pump for White LED Flash Applications General Description 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 VIN and VOUT) makes the AAT3112 ideally suited for small battery-powered applications.
