离线降压LED控制器

MP4000是一款高效率降压变换器，用于驱动高亮度发光二极管（LED）。MP4000采用浮动降压变换器结构，以驱动外部MOSFET。其电感器电流通过边界传导模式进行调节，该模式在续流二极管中没有反向恢复损耗，并可实现功率MOSFET的软导通。这种工作模式可以实现非常高的效率，同时缩小电感值和尺寸。另外，通过控制由外部电阻器采样的MOSFET峰值电流，可以很好地调节LED电流。其300mV的低反馈电压降低了功耗并提高了效率。MP4000可以接受外部PWM或DC信号，以实现突发调光控制。MP4000还具有输出短路保护、最大开关频率限制、欠压锁定保护和过温关断保护功能。 • 恒流LED驱动器\n• 功率MOSFET零电流导通\n• 无续流二极管反向恢复损耗问题\n• 边界模式操作可提供高效率和高可靠性\n• 0.9mA低工作电流\n• PWM或DC输入突发调光控制\n• 打嗝模式短路保护\n• 欠压锁定保护（UVLO）和过温关断保护\n• 110kHz最高频率限制\n• 采用 SOIC8 封装;
