have a big problem with the strong overshoot of the "Source" connection of LNK304 when switching off the DS transistor.
This leads to interference in the transmitter (868MHz).
Tried different output capacitors (55, 100, 150, 360, 500 mOhm). The same applies to various inductors. A Wurth 680uH (744 777 26) is currently installed.
Can someone help me with this?
