Part Number: UCC28065 Because the AC input current is high , so the filter size is too large.
Customer wants to use two filters and two rectifiers to connect with the two channels of the UCC28065.
Is such an idea feasible?
What are the risks?
thank you…
Part Number: UCC28065 Other Parts Discussed in Thread: UCC28056 , Hello, I'm developing a PFC interleaved transition mode.
I know that some non-interleaved transition mode PFC controllers allow you to use an inductor without an auxiliary winding.
For example…
Part Number: UCC28065 Do you have a formula to calculate the on-time, based on the value of Rtset and the voltages applied to the Vinac and Vcomp pins?
Part Number: UCC28065 Over current operation of UCC28065.
When overload operation occurs ,
the 2 gate- drive output , which was previously operated 180 degrees out of phase , is turned off at the same time .

Part Number: UCC28065 Hello, I am using the UCC28065 in a 115VAC, 730W PFC application. I have noticed something curious about the phase interleave.
The application circuit is generally similar to the eval board, with smaller inductors to operate at higher…

Part Number: UCC28065 Hello Experts, My customer downloaded "Interleaved_PFC with UCC28065_SIMPLIFIED.sxsch" from TI.com. Customer opened this simulation model by SIMetrix and it showed the schematic. But customer start simulation, the simulator…
Part Number: UCC28065 Hi
I am designing the UCC28065.
I want to know the inductor value from the calculation tool provided by TI.
There are MINs and MAXs as below, so should I make it medium when designing?
Thanks

Part Number: UCC28065 Hi
My board makes noise at input voltage 90Vac to 115Vac. There is no noise above 115Vac. The resistance of Rcs was changed from 300ohm to 2.7kohm, and it improved.
Is it okay to use the resistance of the Rcs as 2.7kohm? I usually use…
