Product Overview

The CXLE86235 high-power synchronous buck constant current driver is a benchmark solution in the industrial lighting field, supporting 5-45V ultra wide input voltage and integrating 50mΩ Ultra low impedance synchronous rectification MOSFET, achieving 95% conversion efficiency at a switching frequency of 200KHz, can continuously output 5A current to drive 10 strings of high brightness LED arrays, with a peak power of 50W. Adopting TO263-5L industrial grade packaging, combined with three-dimensional heat dissipation architecture and Class 3K ESD protection, it ensures to maintain± at extreme temperatures ranging from -40 ℃ to+125 ℃; 4% current accuracy, perfectly adapted to ultra demanding application scenarios such as automotive grade matrix headlights and industrial grade high pole lights.gIo嘉泰姆

This chip breaks through technological boundaries through revolutionary system integration: the digital adaptive compensation core reduces peripheral components by 85% and supports lossless dimming with 0-100% full duty cycle; The 0.23V precision sampling benchmark is combined with five levels of dynamic current limiting protection to construct a five fold safety firewall for overcurrent/overheating/undervoltage/short circuit/open circuit. Its innovative multi-phase ripple elimination technology achieves an ultra quiet output of<25mVpp, coupled with a 3-second transient response speed, making it the ultimate driving solution for advanced applications such as smart city streetlights and film and television shooting lamps.gIo嘉泰姆
