Hallo,
We are using UCC28065 to build 600W interleaved TM PFC.
But we are facing with a critical problem when we start debugging the circuit.
As you can see in the snapshot below, when we start debugging…
Part Number: UCC28065 Tool/software: Hi team,
Customer have referred to the UCC28065 300W DEMOBOARD.
If the project power level is 350W, the operating frequency is about 165KHz@90Vac.
How to choose the size of Ferrite core, such as PQ, POT or ATQ…

Part Number: UCC28065 Tool/software: Hello Team,
The customer is considering the UCC28065. The customer wants to use R_TSET=47K Ω, which is lower than the recommended value. Is there any information on the on time for this resistor?
Best regards…
Part Number: UCC28065 Hi, Team
My customer use our UCC28065 in their PFC power module, they prefer Dynamic adjust the R_TSET for UCC28065, the detail is as below:
As we know, the R_TSET value is control the Ton time( or max ton time) of the UCC28065…
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?
