1. Preface
This application note describes how to design PCB layout to achieve high reducing noise performance. The
countermeasures of recommended PCB layout are shown in this application note. And the AC line noise contrast test
with two types of PCB layout boards is introduced to verify these countermeasures. Subsequently, the improvement test
which is based on the non-recommended board is also introduced in this application note.
