2.5V-6V输入，0.35A升压白光LED驱动器

MP1518是一款升压变换器，可用于驱动单节锂离子电池为多达6个串联的白光LED供电。MP1518 使用电流控制模式和定频架构来调节 LED 电流，并通过外部电流采样电阻来检测 LED 电流。其 104mV 的低反馈电压降低了功耗，提升了效率。其OV引脚监测输出电压，并在由于开路而出现过压情况时关闭变换器。\n\n MP1518 具有输入欠压锁定（UVLO）保护、限流保护和用来在输出过载时防止芯片损坏的热过载保护。MP1518 采用 6引脚 TSOT23封装 或 8引脚QFN (2mm x 2mm)封装。另外还提供了非常适用于低EMI 应用的MP1518DJE。 • 集成功率 MOSFET\n• 可驱动多达6个串联的白光LED\n• 效率高达87%\n• 超过1MHz 固定开关频率\n• 开路负载关断\n• 104mV 低反馈电压\n• 软启动/PWM调光\n• 欠压锁定（UVLO）保护、过温关断保护\n• 内部限流保护\n• 采用 TSOT23-6 和 QFN8封装;
