The AAT3112 is a high efficiency 500mA charge pump that is ideal for white LED flash applications. It operates with an input voltage range of 2.7 to 5.0 volts and can provide a constant 200mA output load current and up to 500mA of pulsed current.
The AAT3112 is a member of the Total Power Management IC family that provides a regulated output voltage. It operates with an input voltage range of 2.7V to 5.0V and can deliver a constant 200mA output load current, with up to 500mA of pulsed current capability.
The device features a low external parts count requiring only two flying capacitors and small bypass capacitors, making it suitable for small battery-powered applications. It includes thermal management protection, built-in soft-start circuitry, and a high charge pump switching frequency that enables the use of very small external capacitors.
