The CXLE8285 a step-up converter designed for driving up to 7 series white LEDs from a single cell Lithium Ion battery. The CXLE8285 uses current mode, fixed frequency architecture to regulate an LED current, which is measured through an external current sense resistor. Its low 200mV feedback voltage reduces power loss and improves efficiency.The CXLE8285 includes under-voltage lockout,current limiting and thermal overload protection preventing damage in the event of an output overload.Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency. Internal soft start function can reduce the inrush current. Tiny package type provide the best solution for PCB space saving and total BOM cost.

      CXLE8285是一个升压转换器,用于驱动多达7个系列的白色发光二极管,是由一个单细胞的锂离子电池。该CXLE8285采用电流模式，固定频率的结构来调节LED电流，这是通过一个外部电流检测电阻测量。低电压200mV的反馈，降低功率损耗和提高效率。
