BCT3144 Overview
The BCT3144 is a dual LED flash driver that provides a high level of adjustability within a small solution size. The BCT3144 utilizes a 2-MHz or 4-MHz fixed-frequency synchronous boost converter to provide power to the dual 1.5A constant current LED sources. The total LED current the BCT3144 boost can deliver is 1.5A (ILED1+ ILED2).
