RE: UCC28070A: Does TI have 2.5KW or up reference design?

Ray DiCecco

Hi Jimmy, Unfortunately, TI currently does not have a reference design for the UCC28070x above 800W. There is an 800W design for the UCC28070: www.ti.com/.../PMP40261 . (Note that the A and non-A versions of this product are essentially the same. The difference…

Hi Selvam, Unfortunately, we do not have an EVM with and isolated bridgeless PFC. This is a reference design for a bridgeless PFC, but it is non-isolated: https://www.ti.com/tool/PMP40261 The following app note describes how to use our UCC28070 PFC controller…

RE: TIDA-00779: Increase power rating depand on TIDA-00779

Hely Zhang

Hi, Jimmy Traditional boost PFC are suggested to be under 4kW with >180VAC input voltage, if the input voltage is even lower or the power rating >4kW, suggest to design with interleaved boost PFC topology, to reduce the current stress and power loss…

RE: UCC28070: Questions about inductor selection in bridgeless configurations

David Huang33

Resolved
Hi Kaji, since each PFC inductor need to cover full load at one half main line cycle, so the peak current through each inductor is almost two times compare to interleaved PFC mode. For the peak current requirement, you need a bigger size for PFC inductor…

Hi user4537791, if you look at Vinac and AC voltage, there is a very high spike during the current distortion, please double confirm why there is a spike here. unfortunately I can see clearly the schematic after zoom in. in the datasheet page 21 at paragraph…
