1.2MHz,3V-24V Input High Efficiency Boost White LED Driver CXLE8858 is a step-up converter designed for driving up to 7 series white LEDs from a single cell Lithium lon batleU.

   产品概述 返回TOPR94嘉泰姆

The CXLE8858 is a step-up converter designed for driving up to 7 series white LEDs from a single cell Lithium lon batleU . The CXLE8858 uses current mode， fixed frequency architecture to regulate an LED FXUUHQW ，Zhich is measured through an external current sense resistor. Its low 200mV feedback voltage reduces power loss and improves efficiency The CXLE8858 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 lRZ operation current with high efficiency. Internal soft start function can reduce the inrush currenW. Tiny package type provide the best solution for PCB space saving and total BOM coVW
