  • TPS61195 Flashes to 100% on Initial Enable and Brightness Change.

    Other Parts Discussed in Thread: TPS61195 , LP8555 We're using a TPS61195 in Linear Output mode, with PWM input control (SEL1 grounded, SEL2 floating, "Analog Mode, PWM Interface"). After the board powers up, the software starts its PWM timer…

  • TPS61195 allows different currents indifferent channels?

    Other Parts Discussed in Thread: TPS61195 Hello, Does the TPS61195 allow the current to be set to different levels in each channel? If not, do you know of a ti.com controller that does? LED current is 30mA to 100mA. We like the use of a boost controller…

  • Re: LED Backlight Driver for LCD-TFT Display Panel

    Resolved
    I suggest TPS61195. You can tie 2 of its IFB pins together to get 60mA for configuration 1 and you can tie all of its strings together to get the 200mA configuration.

  • Re: Atypical power supplies.

    Gordon, How many LEDs do you have in parallel and how much current do you want to drive through each of them? We have a wide variety of multi-channel LED drivers, but most are boost converter based: TPS61195 as an example: http://focus.ti.com/lit/ds…
