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
