LM5160-Q1: Layout questions on LM5160-Q1 Fly-buck topology

Part Number: LM5160-Q1
Other Parts Discussed in Thread: LM5160

Hi,

My customer is doing LAYOUT design on LM5160-Q1 Fly-Buck Topology.   Please let us know the following questions.

  • Is it better to shield "the connection between the SW pin (12 and 13 pins) and the transformer" with AGND/PGND?
  • Is it better to shield "AGND/PGND plane" above or below the land-line, including the IC and transformer pins?

If you have any example of LAYOUT design, please advise us.

Thanks and best regards,
M.HATTORI
