1A Flash Driver

The AS3683 is a low-noise, high-current 1A Charge Pump designed for camera Flash LEDs and LCD backlighting applications. The current sinks are capable of driving up to 960mA of load current.
The AS3683 integrates two independent current source blocks for driving a single Flash LED (CURR11 to CURR13) with up to 480mA, and general purpose LEDs (CURR2 to CURR4) with up to 160mA LED The general purpose LEDs are controlled individually and CAN be used for backlighting, but also in support of an RGB funlight or a movie indicator lamp. To meet high-flash cur rent requirements (up to 960mA), both current source blocks CAN be connected together (CURR11 to CURR13 and CURR2 to CURR4).
