Other Parts Discussed in Thread: LM5122

Hi,

I'd like to ask about basic question of LM5122(synchronous boost controller).

In product folder(below), it is described that max output current is 15A.

I think it depends on external FET, so I want to know background of the description.

Hi Yaita

You are right. Since LM5122 is a controller, its current capability depends on MOSFET selection.

Hi Eric.

Thank you for the reply.

I see there is no basis for the value.
