Hello dear EEVblog forum members,
I have a problem with a buck converter.
It is designed using the GS61008 GaN driven by the LMG1205 pre-driver.
The problem that appears is that during turn-off of the HS transistor, the transistor turns itslef back on.
Please see the attached pictures.
The converter, and the measurement points:

Layout (GaN devices are on the other side of the board)

Scope measurement, where you can see the turn-on:

Phisical board

Do any of you have any experience with this?
Would appreciate any help with this.
Thank you and best regards,
Relu
