LM25184EVM-S12: For 24V-in to 12V-out / I-out 2A

Part Number: LM25184EVM-S12
Other Parts Discussed in Thread: LM5157, LM25184, LM5156

Hi Sir,

My customer would like to find an isolated DC/DC converter device for 24V-in to 12V-out / I-out 2A.
They also would like to test this EVM to verify the function. May I know if this EVM can meet their request or not? what components need to change spec?
If it can't, could you please advise the suitable device?

Hi,

You can use the calculation tools to check it. Maybe you should change the transformer. The link is shown as follows. Thanks

Hi henry,

24W is likely too high for the LM25184, especially if Vin-min is below 24V. You might consider the LM5156 flyback controller or the LM5157 flyback converter.

Hi Sir,

May I know if they could use the LM5157EVM-SEPIC to verify the function?

Hi Henry,

A SEPIC is typically non-isolated. I think you need a flyback.
