    Hello,

    Thank you for considering the LM3481 in your design. 

    I think given your power requirements, you can use the LM3481

    Yes, there are some designs that can be used to output 24V @ 2A from your input ranges. I would recommend taking a look at PMP8536 and PMP8711 as a starting point, which use the LM3481 in a boost converter configuration.

    There is also the LM5155, which is a newer version of the LM3481. Compared to the LM3481, it has lower quiescent current and higher efficiency. The LM5155BST-EVM also has your input range and can generate your output.
