AAT3177A Datasheet | Skyworks Solutions

DATA SHEET High Current, High Efficiency Charge Pump with Auto-Timer General Description The AAT3177A is a high output current, high efficiency, low noise, low profile charge pump DC/DC converter. The device is ideal for multi-functional LED photo-flash applications where solution cost, size, and efficiency are critical. The AAT3177A is capable of driving a regulated output current up to 800mA. Output current levels can be easily programmed in 16 steps through Skyworks' Simple Serial Control™ (S2Cwire™) interface controlled by a single microcontroller GPIO line. This allows smooth transitions and flexible adjustment of brightness in flash or other lighting modes. The maximum...
