  • LM25149-Q1EVM-2100: At 6Vin, the 5V output is not regulated for output currents greater than 2.5A

    TI Thinks Resolved
    Part Number: LM25149-Q1EVM-2100 Other Parts Discussed in Thread: LM25149 , We want to design a 12V->5V circuits that is very efficient from 5mA to 4A. We also want the output to maintain regulation as the input drops down to 5.85V. I looked at the LM25149…
