Other Parts Discussed in Thread: LM5148

Tool/software:

We want to design a DCDC power with the LM5148 + LMG2100 output 25A@12V, and input 55V. Does TI have any reference designs for us?

Hi Nan Li,

We don't currently have a reference design using the LMG2100 + LM5148 55V->12V @25A. However we see the LMG2100 has good efficiency in this type of application when paired with the correct controller. I will send you an email with TI's field applications engineer to explore this application.

Can you show us some typical design solutions for this type of application? Which correct controller do you recommend using?
