  • RE: LM5012-Q1: LM5012 intermittent operation

    Hi Nobert, I would check the feedback voltage along with switch node in both fail and pass devices to check if the feedback voltage is as expected. If the injected signal is as expected, then it is LM5012 issue else we need to check injected ripple components…

  • LM5012-Q1: EMI Problem

    Part Number: LM5012-Q1 Tool/software: Hi to all, i finished my design with the LM5012-Q (Vin: 19.2V to 57.6V, Vout: 18V 12W). Circuit works fine after some capacitor improvement. The issue now is, that EMC Test EN61000-6-3 E Field SAC 3m failed at 120MHz…
