Flash driver IC delivers high-intensity WLED lighting for camera phones
( 01 Sep 2008 )
The AAT1282 is said to be the industry’s first 2A flash LED driver IC capable of delivering high intensity light from White LEDs (WLEDs). Operating across a 2.7 to 5.5V input, the devicc is designed for LED photo flash applications in a variety of single-cell Li-ion powered products. The high efficiency, high current step-up converter features two output current sinks each providing a regulated 1A current. The two LED current sources share the output current equally.
