Hi Expert,

I would like to know the difference LM5122-q1 and LM25122-q1, except Max input voltage and switching frequency. Is it ok for p2p drop in? Thanks.

Hi Elec Cheng,

There is no difference except the parameters you mentioned, absolute voltage max Vin, switching frequency, and cost
Functionally, they are identical. Could you please explain what do you mean by P2P drop in?

The customer is looking for pin2pin replacement due to shortage. They don't want to change hardware. This is why I ask P2P drop in. Thanks.

Hi Elec Cheng,

Yes LM5122 and LM25122-Q1 are practically the same, just the absolute values and Fsw are different, so P2P replacement could be possible.
