Part Number: UCC38C44 Tool/software: As the title suggests, why is the feedback (FB) pin shorted to ground? It is supposed to be the input of the Error Amplifier. Now the loop is fed into the output of the Error Amplifier (COMP pin).

Part Number: UCC38C44 Hey,
i design a DCM Flyback (DC to DC) Converter with the UCC38C44.
My problem is the Voltage Feedback Compensation in the description.
How to do this with a DCM Flyback or are the formulars the same ? Especially the Open Loop…
Hi BHARATH PRABHU,
I have had no response from you for a while, and am therefore going to mark this post as closed. Please feel free to open another post if you feel there are questions left to answer.

Part Number: UCC38C44 Hi team,
I had a few questions regarding the SLUA274A app note in relation to the UCC38C44.
In section 2.5, under the equation for the snubber calulcation, equation 13 has a variable labeled "T". What does this refer to, turns…
Part Number: UCC38C44 I am working through the transformer design in SLUA274A and get a different Dmax after the turns ratio has been increased from 5.6 to 6, 0.419 instead of 0.347??
Can anyone confirm this?
Thanks
Steve
