  • TPS61185: TPS61185 current sink open behavior

    TI Thinks Resolved
    Part Number: TPS61185 Other Parts Discussed in Thread: TPS61177A , TPS61187 , , TPS61183 From customer test result, the boost output voltage is OVP voltage when no LED is attached. It seem not match with D/S. Is it normal? Thanks. Is the behavior the same…

  • RE: TPS 92640 work at a voltage of 80 V

    Dmitriy: The maximum operating input voltage of TPS92640 is 85V. The EVM you put is for TPS61183/7. I don't know what schematic change you are talking about. Can you explain more clearly? David Zhang

  • Re: WLED driver for 7" LCD

    Resolved
    What type of dimming, PWM or analog do you prefer? If you want precise matching of the LED current per string, then I suggest one of the TPS61181/2 or TPS61183 with 3 of the strings disabled. Using those parts, you will need to apply a separate 5V to…
