专为1/8扫以下扫描屏设计之内建16位灰阶PWM恒流LED驱动器

MBI5151是专为LED全彩显示屏应用设计的驱动芯片，使用者可选择16位或14位的脉波宽度调变功能来达成灰阶控制。MBI5151内建16位位移缓存器可以将串行的输入资料转换成每个输出通道的灰阶像数。MBI5151的16个恒流输出通道所输出的电流值不受输出端负载电压影响，提供一致并且恒定的输出电流。MBI5151的使用者可以经由选用不同阻值的外接电阻来调整MBI5151各输出级的电流大小。除此之外，MBI5151的使用者还可以藉由可程序化的电流增益调整来调整64阶的整体LED的驱动电流。 MBI5151内建SRAM的创新架构，可支持最高8扫LED扫描屏。使用者仅需送一次完整的帧数据(frame ·01 No. of Output Channel ：16 \n·02 Max.
