Hi,

I am using TPS6108x to drive a LCD's LED backlight.

But how to regulate the output voltage and current?

The TPS6108x datasheet show the typical applications on figure 23 , but it seems that  not tell me how to regulate the output voltage and current.

There is no regulate register on FB pin.

So in this appliacations , how to regulate the output voltage and current?

Thank you .

Best regards,

Liu.
