    Hi Qianqian,

    The maximum current for each current sink is 50mA. The reason that we have a lot of current in that table is for different current setting. We have provided a lot of current setting for different customers. Since our LP8556 can change the maximum setting through I2C. But may be some customer doesn't have the I2C interface. So we will provide some default current setting for them. if you have the I2C in your system, you can adjust the maximum current by yourself.
