Hi,
I have created a circuit using TPS23756.
Now, I am doing noise countermeasure of the circuit.
I made various countermeasures, but as you can see in the attached diagram red it is possible to reduce the noise by adding a capacitor.
A capacitor was connected between the pattern between L905 and TS901 and the ground (PGND) on the secondary side.
Normally, capacitors are not placed at such positions due to measures against noise of the insulation circuit.
Is it possible to connect a capacitor to the red position?
(Added capacitor)
4700 pF / 2 kV x 1
1000 pF / 2 kV x 1
Best Regards,
