Part Number: LM5146-Q1
Other Parts Discussed in Thread: LM5143A-Q1

Tool/software:

Can LM5146-Q1 output a current of 40A or higher? If there is a method, how is it implemented?
How to adjust the design when there is a significant transient change in current, such as from 100mA to 10A or higher

    Hello,

    It really depends on the power stage components, Vin, Vout, Fsw, etc. Please use the quickstart calculator (see link in product folder) to assist with the design. Alternatively, consider a two-phase design with the LM5143A-Q1.
