Hi,
In datasheet of UCC21750-Q1 gate driver, there is description that "No PCB trace or copper is allowed under the gate driver. A PCB cutout is recommended to avoid any noise coupling between the input and output side which can contaminate the isolation barrier"
For UCC21750-Q1 gate driver and TO247 Sic mosfet, in PCB layout is it possible to place a switching unit under the UCC21750-Q1 (placing other side of the PCB) without putting a trace or copper under them. Or how many millimeters is needed between switching unit and PCB not to interfere the gate driver.
Thanks in advance.
