Part Number: LM5148-Q1 Other Parts Discussed in Thread: LM5148 , LM5149 Hello,
I'm currently using the LM5149-LM25149 Calculator for the LM5148 Buck Converter (as the LM5148 one's is not available).
For the buck inductance calcul, I followed the…
Hello Cuong,
Please can you fill out the calculator spreadsheet with your specification so I can check your design against the recommendations, this is a good place to start, thanks.

Hello Shunsuke,
The LM5148 requires logic level MOSFETs with a miller plateau of ~3V.
Please use the design calculator to determine losses for a given spec.

Depends on if you need two phases. If you only need one phase, then the LM5148 is an option (and this is stackable to two phases if needed).
Typically, we only need two phases if the output current exceeds 20-30A (depending on Vin-max, Fsw, max ambient…
