www.DataSheet4U.com AAT3172 High Current LED Flash Driver Charge Pump IC General Description The 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. The dual charge pump in the AAT3172 is capable of delivering 600mA peak 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. The tri-mode (1X/1.
