General Description The AAT3176 is a high output current, high efficiency, low noise, low profile charge pump converter IC, ideal for multi-function LED photo-flash applications where solution cost, size, and efficiency are critical. The charge pump is capable of delivering up to 500mA of output current and can be easily programmed in 16 steps with a single GPIO output through Skyworks' S2Cwire™ (Simple Serial Control) interface. This allows smooth transitions and flexible adjustment of brightness in flash or other lighting modes.
