The AS3649 is an inductive high efficient DCDC step up converter with two current sources.

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 2x1000mA(2x1250mA with current boost) or 2000mA and automatic load balancing for two LEDs.
Automatic current adjustment for low battery voltage.
PWM operation for lower output current for reliable light output of the LED; can run at 31.5kHz to avoid audible noise.
Protection functions: Automatic Flash Timeout time.
