Part Number: UCC2818 Other Parts Discussed in Thread: UCC28061-Q1 , , UCC28061 , UCC28C43-Q1 , UCC28C43 Hi,
My requirement is: input 30V~500V DC, output 12V1A, isolated, can I design this circuit with UCC2818A-Q1, or UCC28061-Q1, UCC28707-Q1? Automotive…
Other Parts Discussed in Thread: UCC28061EVM , UCC28061-Q1 , UCC28070 , PMP Hi,
I need a PFC IC that can handle at least 3kW, preferably up to 5kW.
I am considering the UCC28061-Q1 and the eval brd for this (UCC28061EVM) supports up to 300W only.…
Other Parts Discussed in Thread: UCC28061 Hi,
In continuation of the previous post which I made ("UCC28061: Power MOSFETs blown up sometimes") I want to share the new measurement with you and exploring the possible issue with the MOSFETs in this design…

One of my customers uses UCC28070 for their mass-production.
At this moment, they have the following questions…
Part Number: UCC28061 Dear TI Team,
We've encountered an issue with our design that employs the UCC28061 with two power MOSFETs, which are experiencing occasional failures.
Originally, we utilized the STP25NM60ND MOSFETs for this purpose. However…
As explained, when the COMP voltage exceeded 222 mV, both GDA and GDB output pulses.
[that is because at no load condition if the Comp Voltage is lower than 222mV, then both GDA and GDB will stop the pulse. And at this condition,
GDB output some pulses…
Part Number: UCC28063 Other Parts Discussed in Thread: UCC28061 Dear Expert
Ctm change UCC28063 to UCC28061 ,and system fails to start .The Pin5 COMP is low lever ,other pin voltage are normal.
Below is schemetic ,pls check! 24v8a.pdf
Hello Yasushi-san,
Very sorry for the delay.
To be clear, the app note you cited has the UCC28070 in a semi-bridgeless configuration. That said, the current synthesizer feature that the -070 makes this particular design relatively straightforward…
Hi Willian,
Most of the details are addressed in the two links mentioned above. Please see the link below helps in addition to one above:

Hi Rebecca,
Thank you for the query on UCC28070.
The following app note shows the advantages of semi bridgeless vs interleaved pfc.

At 5KW, interleaved PFC is probably…
