[FAQ] Is there any a simple way to choose the single channel LED backlight driver?

Hi TI LED Driver team,

    I'm a little confused when I choose the single channel LED backlight driver, there are a lot of choices, such as TPS61158, TPS61160, TPS61161, TPS61162, TPS61165, TPS61169, TPS61042 and so on. Is there any simple way to choose this kind of device or is there any recommend devices for single channel led backlight driver? Thanks.

  • Hi,

       Yes, we have some single led backlight driver, and they have some difference form the datasheet.  We can provide a simple way to choose those LED drive as below:


    And you can refer to below test results for dimming performance for those single LED driver:

    And below is the typical voltage offset for those led drivers:


           •TPS61161/5 has good performance at low duty cycle;
           •TPS61169 has better efficiency performance;
