  • RE: LM25145: Conversion efficiency with DCM at 30mA output

    Resolved
    Hi Dice-K, We do not currently model DCM operation in WEBENCH or the quickstart calculator. However, you can try your configuration by suitably modifying the LM5145 or LM5146-Q1 EVMs. Please consider using the LM25141 or the LM25148 controllers…

  • RE: LM5145EVM-HD-20A: Adjusting EVM Output Voltage

    Not in terms of EVMs, but it should be easy enough to modify the LM5146-Q1 EVM if needed. Also, take a look at the 24V output apps example in the LM5145 datasheet.

  • LV5144: LV5144 design assistance

    Resolved
    Part Number: LV5144 Tool/software: Hello, I have designed a 60V nominal (max Vin may be a bit higher, hence why I chose LV5144 and 100V mosfets) to 18V @ 8A buck converter, based on the schematics for the LM5146EVM and the webench suggestions. The…

  • RE: TPS40200EVM-001: 3d design files

    Hi Sunaina, This is an older EVM, so we may not have the PCB design files available. Please consider using the LM5145 synchronous buck controller instead. There are two EVM designs for this controller family that you can refer to: LM5145EVM-HD…
