  • RE: LM5118-Q1: LM5118-Q1 stability issues

    Hello Team, We are using the LM5118 also , along with LMP8646 to limit current so that it behaves as a CC source. We will design the LM5118 for 54.6V with the current limit of 3A. So we expect the LM5118 to behave as CC mode during charging a battery…

  • RE: LM5118: Can LM5118 operate in only Buck topology and unpopulate the Boost low-side MOS?

    Resolved
    Hi Haroon, Thanks for detailed waveforms, the result is confirmed that LM5118 cannot be used as pure Buck topology. And from the waveforms, it can be seen that SS pin didn't restart, COMP is high clamped. It seems that some protection is triggered.…
