Part Number: PMP6712 Good afternoon everyone.
I am developing a project very close to the EVAL PMP6712 example. In my design specifications, I have to allow input voltage: negative and positive (+- 48V). Does this EVAL PMP6712 allow negative input voltage…
Part Number: UCC28950 Other Parts Discussed in Thread: TL431 , , UCC21521 , PMP6712 , UCC27714 Hello Leonardo We happen to have a development case like the PMP-6712 architecture. The input battery voltage is 48-60V, the output voltage is 325Vdc (Robot application…
Part Number: PMP6712 Dear Colin
If we still use the PMP-6712 circuit, from the input end to the primary side of the transformer, the secondary side of the transformer is centre tapped as you suggest, and the output voltage of the secondary side is changed…
also I saw the design with two active FB with an output snubber https://www.ti.com/tool/PMP6712 as well as in one from the competitor, using the same approach to mitigate the ringing through the active snubbing. I don't know if I can post here the links fir…
Part Number: PMP6712 Other Parts Discussed in Thread: UCC28950 Hi all,
I had made a simulation with PSIM of the active buck snubber, but I can't understand the function of C80.
Is it just like C36, C37, C72, C73 to store the energy which comes form…
Hello Eric
I'm sorry but I don't have any more information on the PMP6712 than what is on the TI site. The Excel and MathCad calculators for the UCC28950 will help to design a single power stage and of course the design can then be duplicated. …
Part Number: UCC39002 Other Parts Discussed in Thread: PMP6712 , UCC28950 , UCC29002 , Hello to all friends designers.
I am designing an isolated DC / DC converter with load sharing. I am using the reference design PMP6712 to build DC / DC converter, but would…

Hi, Sanghyun,
Do you have to keep the same transformer and snubber cap or you are open to change the power stage?
I am not sure where you read UCC28950 is not efficient when input voltage is low. 48V input is not low. Can you point me the source of your…
