AS3647B 1600mA High Current LED Flash Driver

The AS3647/47B 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 / assi.

AS3647B Features

* 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 1600mA

* Automatic current adjustment for low battery voltage

* PWM operation for lower output current for reliable light
