Product Overview

        The CXLE86237 ultra efficient synchronous buck constant current driver is an innovative solution in the industrial and automotive lighting fields, supporting 5-45V wide voltage input and integrating 50mΩ Ultra low impedance synchronous rectification MOSFET, achieving 97% industry-leading efficiency at a switching frequency of 150KHz, can stably output 4A current to drive 9 high-density LED arrays, with a peak power of 30W. Adopting TO252-5L reinforced heat dissipation package, combined with dynamic thermal balance technology and Class3A ESD protection, it ensures to maintain± at extreme temperatures ranging from -40 ℃ to+125 ℃; 4% current accuracy, designed specifically for high reliability scenarios such as automotive HUD backlighting and industrial grade panel indicator lights.2Qw嘉泰姆

This chip achieves breakthrough innovation through intelligent system integration: the digital adaptive compensation core reduces 85% of peripheral components and supports 0-90% duty cycle stepless dimming; The 0.23V nanometer level sampling benchmark is combined with five levels of dynamic current limiting protection to construct a quadruple hardware level protection against overcurrent/overheating/short circuit/open circuit. Its innovative multi-phase ripple suppression technology achieves an ultra quiet output of<18mVpp, coupled with a 2-s level transient response speed, making it an ideal driving core for precision applications such as medical equipment backlighting and smart home ambient lighting.2Qw嘉泰姆
