  • LMG3425R030: SOURCE pin and GND pin of LMG3425R030

    TI Thinks Resolved
    Part Number: LMG3425R030 Hello, In the datasheet, SOURCE pin is the power ground while the GND pin is the signal ground. So in the layout, I am wondering if the SOURCE pin and GND pin are connected inside the chip or I need to connect them outside with…

  • RE: LMG3425R030: Half-bridge GaN Lay-out

    Hi, It's hard to quantify, but I can show an example here. Here the yellow trace is the ground return trace and the red is the switch node. As you can see there are some overlap between them, but we controlled it to be minimum so there's a minimal additional…

  • LMG3425R030: Aux power supply current will increase with larger bypass capacitor

    TI Thinks Resolved
    Part Number: LMG3425R030 Other Parts Discussed in Thread: LMG342X-BB-EVM Hello, I am using LMG3425R030 in a full bridge configuration. I have a bypass cap closed to the half bridge which is 136 nF and I have another larger bypass cap relatively far from…
