Other Parts Discussed in Thread: PMP9208, , UCC28630
Hi All,
I have tried to use UCC28631 to contribute the attached schematic, since I am first try to construct the SMPS, I take out the transformer from the EV Board(PMP9208) and install to our circuit for first try. Unfortunately, the output is floating (around 24~20V, sometimes the voltage will bump up to 30V and dropdown again), and it will drop to zero when drain the current.
Is that any possibility or idea which part is not correct? any special thing I need to take care? thanks so much for the help!
Best Regards.
Simon
