  • LM3463: basic questions

    TI Thinks Resolved
    Part Number: LM3463 Hi team, I need some help to select LED control method. I think TI has extensive knowledge of LED control. I have some questions about LED Driver and OP AMP for V-I converter. I plan to configure a circuit that controls 5-10…

  • RE: CCS/LM3463: Driving 6 LED strings using two LM3463

    Hello Ryan, Yes, you will have MOSFET power dissipation issues. As an example, 93.8V - 47.6V = 46.2V, at 460 mA the MOSFET will have to dissipate 21.25W. The MOSFET you have chosen is not intended to dissipate power so it will probably have issues with…

  • LM3463: Does VLedFB falling below 2.5V constitute a System Re-Powering?

    Resolved
    Part Number: LM3463 Hello, The datasheet for the LM3463 specifies that there are two ways to clear faults, by applying a falling edge to the EN pin or performing a system re-powering. My customer is wondering if the VLedFB pin falling below 2.5V constitutes…
