2.5V-6V输入电压，1.3A升压WLED驱动器

MP3302是一款升压变换器，专用于为单节锂离子电池驱动WLEDS阵列。MP3302 采用电流控制模式和定频架构来调节 LED 电流，可以通过外部电流采样电阻来检测 LED 电流。其 200mV 的低反馈电压降低了功率损耗，提升了转换效率。当由于开路出现过压情况时，MP3302将被关断。\n\n MP3302 具有输入欠压锁定（UVLO）保护、限流保护和热过载保护，当输出过载时可防止芯片损坏。\n\n MP3302 采用小尺寸 5引脚TSOT23封装或8 引脚2mmx3mm QFN 封装。 • 内部功率 MOSFET\n• 可驱动多达10个串联白光LED\n• 效率高达87%\n• 单线调光控制\n• 1.3MHz 固定开关频率\n• 负载开路关断\n• 200mV 低反馈电压\n• 欠压锁定（UVLO）保护、过温关断保护\n• 1.3A内部限流保护\n• 采用 TSOT23-5和2mm x 3mm QFN8封装;
