I am making a power supply based on the TFS7704H, which I plan to mass-produce. Input voltage 160-250V AC. The output voltage is 14V 8A. Without power factor corrector. Earlier, I wrote to you.
Now the first layout is assembled, I am engaged in its adjustment.
The first thing I noticed was the lack of stability of the form of voltage at the drain in the absence of load.
Can you give me a direction in which to look for the cause of instability?
The source gives 6A with an efficiency of 86%
