Part Number: UCC28065 Other Parts Discussed in Thread: UCC28061 Hi
Is it possible to design a bridgeless PFC using UCC28065?? Or is there any IC that can achieve CRM bridgeless PFC??
Thank you

Could you help recommend best solution for FAN9673Q? I only find two ch Interleaved CCM.
Thank you!

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. the…
Part Number: UCC28065 Other Parts Discussed in Thread: UCC28064EVM-004 , UCC28061 Dear TI team, I have a question regarding the start/stop point of the winding choke. I have seen in the datasheet of the UCC28065, the start/stop winding turn of the choke is…
Hello,
The links were to a PFC boosts which do not use an sync rectifier. I could not open your schematic and it seems like you have designed flyback converters. Is that correct? Could you post your schematic again please?
In regards to the negative…
Part Number: UCC28065 Hello,
In one of our 600W PFC application, the input voltage can be 100Vac to 240Vac. In the UCC28065 datasheet, the thresholds for BRST and PHB is calculated for low range (90 - 132Vrms) and high range (180 - 265Vrms). The transition…
Part Number: UCC28065 Other Parts Discussed in Thread: UCC28070 Hi there, my name is Kian Fotouhi. I'm an electrical engineering student working on a high-power audio amplifier that will need a transition-mode boost PFC. The specifications will be:…
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?
