Part Number: UCC28065 Tool/software: Hi team ,
I wanna ask if the input line voltage is higher than 10kHz. What kind of the boost CCM PFC IC I can use. (High switching frequency 500kHz up)
Part Number: UCC28065 Other Parts Discussed in Thread: UCC28064 Tool/software: Hi expert
my customer want to use UCC28065 replace UCC28064, this is the schematic of UCC28964, could you please tell what we need to change if use UCC28065
Part Number: UCC28065 Other Parts Discussed in Thread: UC2854A Tool/software: Hi team,
I wanna ask if I use UCC28065 as a PFC converter, can I just use one output.
I don't need interleaving and transition mode,but need high switching. Or you have others…
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

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…
Part Number: UCC28065 Other Parts Discussed in Thread: UCC28064 Hi,
We used UCC28065 for our AC-DC board from 360Vac to 15Vdc, 20A. We are seeing negative current spikes (6A) at primary side of the flyback transformer. This is happening at irregular intervals…
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:…
