High Efficiency Synchronous Boost Converter With Dual Independent 1.5A Current Sources BCT3144 High Efficiency Synchronous Boost Converter With Dual Independent 1.5A Current Sources GENERAL DESCRIPTION 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). The dual 128 level current sources provide the flexibility to adjust the current ratios between LED1 and LED2 with each driver capable of delivering a...
