  • TPS543820: simulation tab

    TI Thinks Resolved
    Part Number: TPS543820 Hi, I am working in the Webench design for this part number: TPS543820. The simulation tab is not enabled for this chip. Do you know when would this be available? Cheers

  • TPS543820: Power problems

    TI Thinks Resolved
    Part Number: TPS543820 I created a power supply that generates a 3.3V voltage from 12V to drive some LEDs. These need a larger current under full load. The power supply should be able to deliver a maximum current of 4A at 3.3V. With the Webench Designer…
