  • LM5104: External gate resistor app note does not mention load

    TI Thinks Resolved
    Part Number: LM5104 I'm following the instructions for external gate resistor selection (SLLA385A), and the app note describes a process where oscillations at the gate of the FET are probed to characterize unwanted ringing. The app note does not…

  • LM5104: simulation stop between 60-65ms

    TI Thinks Resolved
    Part Number: LM5104 Hello Team, I'm posting on behalf of my customer. Please see the inquiry below: Basically we work with inverter circuit using LM5104 driver IC. Now At the output of LC filter I got the sine wave as expected but while we simulate…

  • LM5104: Uneven propagation delay

    Resolved
    Part Number: LM5104 I'm doing my initial testing with the LM5104, and observing some odd asymmetry in the propagation delay during IN rising versus IN falling. My configuration in this test: Vdd = Vhb = 12V 10ohm Gate resistors for HO and LO RT…

  • LM5104: Duty cycle accuracy and propagation delays at high frequency operation

    Resolved
    Part Number: LM5104 I've designed a current regulator around LM5104, intending to operate at around 500kHz (period = 2us). I knew there would be some minimum functional duty cycle and that it would depend on the switching frequency and various delays…
