Product Overview

The CXLE86233 industrial grade synchronous buck constant current driver is a groundbreaking high-density power solution developed specifically for intelligent lighting systems and high-power display devices. It supports 5-45V wide voltage input and integrates 80mΩ Ultra low resistance synchronous rectification MOSFET, achieving 95% peak efficiency at a fixed frequency of 200KHz, can stably output 3A current to drive 10 strings of LED arrays, with an output power of up to 15W. The chip adopts automotive grade SOP8-EP packaging, built-in dynamic thermal compensation module and Class 2K ESD protection, and can maintain± in extreme environments from -40 ℃ to+125 ℃; 4% current accuracy, perfectly suitable for high reliability scenarios such as industrial lighting and vehicle displays.Otx嘉泰姆

This device achieves revolutionary breakthroughs through intelligent system integration: the digital compensation core reduces peripheral components by 75% and supports zero loss dimming at 0-100% full duty cycle; Combining 0.23V precision sampling benchmark with multi-level current limiting protection, a five fold safety protection system is constructed from the chip to the system. Its innovative valley current control technology achieves ultra-low ripple output of<35mVpp, coupled with fast dynamic response characteristics (<5s recovery time), making it an ideal choice for demanding applications such as smart street lights and medical equipment backlighting.Otx嘉泰姆
