LM3481 : Hello I am trying to get output 24 2a by inputting Vin 6.2 ~ 7.4v using lm3481. Can I get output using lm3481?

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There is also the LM5155, which is a newer version of the LM3481.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.
