  • LM5176-Q1: Gate Drive Resistors

    Resolved
    Part Number: LM5176-Q1 Hi Team, Is it okay to only have gate drive resistors between HDRV and the FET? Or do gate drive resistors always need to be balanced with one added to the H outputs and one added to the L outputs equally? Thanks, Jared

  • LM5176-Q1: FET loss calculation question

    Resolved
    Part Number: LM5176-Q1 Hi, I have a question about loss calculation as follows. When in buck mode, Why is QL1 calculated only as conduction loss? (Is QL1 calculated as conduction by replacing diode in buck mode?) Shouldn't switching loss be considered?…
