Please note: this product is being discontinued and is not recommended for new designs.\n\nThe AAT3172 is a high output current, high efficiency, low noise, low profile charge pump DC/DC converter, ideal for multi-function LED photo-flash applications where solution cost, size, and efficiency are critical.\n\nThe dual charge pump in the AAT3172 is capable of delivering 600mA output current. Two current-controlled paths are available for users of dual flash LEDs that prefer current matching. Each LED channel can be easily programmed in 32 steps with a single GPIO output through the AS²Cwire™ (Advanced Simple Serial Control™) interface. This allows smooth transitions and flexible adjustment of brightness in flash or other lighting modes.\n\nThe tri-mode (1X/1.5X/2X) operation of the internal charge pump offers excellent power efficiency for both flash and movie modes. Combined with a low external parts count (two 1µF flying capacitors and one small bypass capacitor at VIN and OUT), the AAT3172 is ideally suited for small, battery-powered applications.\n\nThe AAT3172 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. The shutdown feature disconnects the load from VIN and reduces quiescent current to less than 1.0µA.\n\nThe AAT3172 is available in the Pb-free, thermally-enhanced, 12-pin 3x3mm TDFN package.\n\nPlease note: AAT3172 is not recommended for new designs.
