LM25119: 25145

Syed Shahnawaz

Part Number: LM25145

I am using this controller for my design, but I am confused about current limitations of 20A. How did you defined this current limit?

I am designing my converter having 30A load current. Isn't output current related to Mosfets and inductor?

Can I use this controller for my design?

Thank you

Hi Syed,

Yes, you can use the part for 30A design.
Depending on Vin/Vout, you may need 2phase for 30A.

Thanks

Hi Syed,

I suggest to use 2phase for 30A design to achieve better efficiency and thermal performance.
