Other Parts Discussed in Thread: TL431 , UCC28740 Hi all, I want to make a smps which want to reference PMP12027 design, but I cannot find the datasheet/detail of the transformer, would any one can reply where to get the datasheet of transformer? (I check…
Hi David,
The 3855 transformer is a good choice, available off the shelf. Saved me from making email request to the transformer vendors. Thanks!! I was thinking of adapter priority, somehow you managed to read my mind. :-) DEN as with Option#3 was what…
Hello Downey,
This design is 24V. Major changes would be needed to convert it to 48V, such as transformer change, checking for voltage for everything on the output side. Note: that most of the things on the 24V bus can't support 55V. The current range…
Hardy,
There is an existing reference design using UCC28740 for 48-V output at 30W:

This would be a good starting point for your design. Please take a look to see if it meets your requirements.
Thanks,
