Part Number: PMP8740 Other Parts Discussed in Thread: UCC27714 , UCC28950 Hi,
We would like to design DC-DC converter with output of 3KW, 28V, 108A by using PMP8740 reference design.
Input will be 390 to 400VDC.
Is it possible with this to get 3kW output…
Part Number: PMP8740 Tool/software: Hi Roberto,
With reference to the PMP8740, would like to know if the design could be modified for 2 outputs of 32V, 30A each. As per the design, until the PFC Stage, everything would be the same but we would have…
Dear Meet,

Need help in impementing the following requirements. For the reference boards I saw the PMP8740 that can provide the required outputs. Can I change the output…
Hello Mohammed,
As DC/DC stage I suggest to select phase shifted full bridge, like in the PMP8740, even though this design is a bit too much power.
If 1.2kW is just peak and the average power is lower, you can have a look also to the lower power version…
