I have a question about LM25005.

Does this Ic have light load mode?

I am looking for the IC of PWM mode only.

Hi,

I don't think this part has PFM mode (light load mode). You might want to take a look at LM46002 which has a light load mode and synchronous buck and internally compensated.

Thank you for your answer!

I understood that LM25005 does not have PFM mode.

And we think that TPS5420 does not have PFM mode(light load mode).
Is the above recognition correct?
