  • LM3150: LM3150 chip temperature increase too much with output voltage increase

    TI Thinks Resolved
    Part Number: LM3150 Other Parts Discussed in Thread: CSD18563Q5A , LM25145 Hi, I am uisng LM3150 , so far it is good. But I am curious one thing for chip temperature. Test setting is: 24V input, wihout loading, with the different output voltage. The question…

  • RE: LM5145: principle of adaptive dead-time

    Hi Yifan, The Miller plateau voltage of the FETs should be in the range of 3V to 5V, so that 7.5V gate drive amplitude (= Vcc) provides adequate overdrive at turn on. What FETs are currently used? As an example at 60V, take a look at the CSD18563Q5A…

  • RE: LM5143-Q1: Design issue for LM5143

    Resolved
    HiZhang, This is a 100V FET with high Rdson and hih Qrr. If Vin-max is 48V, thenyou can use a 60V FET. This will give lower power loss. Take a look at TI's NexFET portfolio of 60V FETs. In partiicular, you can use the NexFET calculator tool here: …
