5V-28V输入电压，12通道升压WLED控制器

MP3389是一款具有12通道电流源的升压控制器，用于驱动大型LCD面板背光应用中的WLED阵列。MP3389采用电流控制模式和定频架构。其开关频率可通过外部频率设置电阻器进行调节。它驱动一个外部MOSFET，可将输出电压从5V输入电压升至28V。MP3389可将每个LED串中的电流调节至预设值，该预设值由外部电流设置电阻器设置。MP3389 采用12个内部电流源以实现电流平衡。灯串之间的电流匹配精度可以达到2.5％。其 600mV 的低平均反馈电压即降低了功耗又提升了效率。PWM调光功能通过外部PWM输入信号或DC输入信号实现。调光PWM信号可以在内部生成，而调光频率则由外部设置电容器设置。 • 高效率和小尺寸\n• 输入电压范围：5V 至 28V\n• 可用于12串WLED的平衡驱动器\n• 每串最大60mA\n• 灯串之间的电流匹配精度为2.5％\n• 可调开关频率\n• PWM或DC输入突发PWM调光\n• LED开路保护和短路保护\n• 可调过压保护\n• 欠压锁定（UVLO）保护\n• 过温关断保护\n• 28引脚TSSOP封装和28引脚 SOIC封装;
