  • RE: LM25141-Q1: The Iout max of LM25141-Q1

    Resolved
    Hi Charles, Thanks for the question. There is no pre-defined maximum for the output current as this is a controller. It just depends on power stage component selection (FETs and inductor) and the PCB design as these relate to the achievable thermal performance…
