• LM5104: Clarification on pull-up/pull-down gate drive resistance

  

  Reece Jahnke

  Resolved

  Part Number: LM5104 Tool/software: Hello! My coworker and I have been arguing about the properties of this chip. The datasheet notes that the maximum peak pull-up current is 1.6A, and peak pull-down current is 1.8A at 12V. I am assuming this means that…

  Jim G

  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

  

  Jim G

  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…
