1A，降压式LED驱动芯片

为高效率、恒电流、降压型直流对直流转换器，仅须透过4个外接组件即可为大电流的LED照明提供稳定之电流。MBI6651的Hysteretic PFM模式能提升效率至96%，其输出电流可透过不同阻值的外接电阻来调整各输出级的电流大小，且在DIM脚连接脉宽调变(PWM)讯号进行调光控制。此外，内置的启动保护可限制电源打开时所产生的突波电流。MBI6651的特色还包括一系列保护IC装置，包括欠压锁定保护(UVLO)、过热保护机制、LED开路与短路。为了确保系统稳定度，MBI6651内置散热保护机制与散热片，加强散热功能并避免芯片过热(165°C)，因此系统可以在大量电流通过时稳定运作。MBI6 • 01 Max.
