LM25122-Q1 - About external components of dual phase

Guru 21045 points

Hi Team,

 

Our customer are evaluating the dual phase of LM25122.

Therefore, we would like to know the value of external components (Loop , slope, etc)

Could you please send the calculation tool of the external components to me if you have any information?

 

And, I have one more question.

Is there any concern if they set “Vout=48V”?

We understand that the recommended switch node voltage is 50V(max).

However, they worry about margin of the switch node voltage.

 

< customer requirements >

-Vin=12V(typ)

-Vout=48V

-Iout=around 8.5A (Pout=400W)

 

Regards,

Kanemaru
