Description	2000mA High Current LED Flash Driver
Datasheet	AS3648-austriamicrosystems.pdf

The AS3648 is an inductive high efficient DCDC step up converter with two current sinks.

The DCDC step up converter operates at a fixed frequency of 4MHz and includes soft startup to allow easy integration into noise sensitive RF systems.

The two current sinks can operate in flash / torch / assist (=video) light modes.

High efficiency 4MHz fixed frequency DCDC Boost converter with soft start allows small coils - Stable even in coil current limit.
LED current adjustable up to 2000mA.
Two LED operation or single LED operation (com- bine LED_OUT1 with LED_OUT2).
Automatic current adjustment for low battery voltage.
PWM operation for lower output current for reliable light output of the LED; running at 31.25kHz to avoid audible noise.
Protection functions: Automatic Flash Timeout tim.
