LM25118EVAL: Radiated noise of LM25118EVAL
This is a related question.
Hello.
Although the noise due to the snubber could be reduced, the output voltage fluctuates when the input voltage is set to 30V or higher.
There is a voltage drop of VCC.
As I announced in the previous question, a snubber circuit (10Ω + 2000p) is inserted between GATE and SGND of Q1-Q2 of FET.
Please comment on the insertion location and constants.
