Part Number: UCC28070-Q1 Hi,
I have a couple of questions for current consumption of the datasheet P3.
VCC current enabled TYP9.0mA、MAX12mA is whole device current consumption correct?
What's the reason why difference between Typ and Max?
The datasheet…
Part Number: UCC28070-Q1 Hi,
The datasheet specifies below Dmax value for Dmax typ 95% case,
I need Max/Typ/Min for specific Dmax such as 90% typ case.
Can you provide Dmax value for Min/Max for specific typ case? Or formula?
Min XXX %
Typ Set specific…
Hello Swetha,
Unfortunately, we do not have a PSpice model for UCC2818A-Q1. We do have a PSpice model for the UCC28180 (single-phase CCM PFC) and the UCC28070 (interleaved CCM PFC).
Regards,
Jonathan Wong
Hello Choi,
Thank you for your interest in the UCC28070 family of PFC controllers.
In the earlier Webench, 220nF for Cfa and Cfb was a programming mistake. 220nF would make the RC filtering for noise on the CSA and CSB signals too much and round off the…

One of my customers uses UCC28070 for their mass-production.
At this moment, they have the following questions. Could you…
Part Number: UCC28070-Q1 Other Parts Discussed in Thread: UCC27524 , UCC28070 Hello Team,
We are using UCC28070 PFC IC and UCC27524 Driver IC for Inhouse on board charger development project.
The testing is in work.
We are not getting the PFC output…
Part Number: UCC28950-Q1 Other Parts Discussed in Thread: UCC28950 , UCC28070 , UCC28951 Tool/software: Hi ,
Input is 400V DC(from Front end PFC), output is 300V to 480V DC for EV battery charger ,is it advisable to use PSFB UCC28950 controller IC for…
Hello Kobayashi-san,
Thank you for your interest in the UCC28070 PFC controller.
Since your design is targeted for high-line-only input range (170~264Vac), I strongly recommend that you use the revised inductor design procedure found in the UCC28070A…
Part Number: UCC28070-Q1 Other Parts Discussed in Thread: UCC28070 Dear,
I used UCC28070 to design 6.6KW project， when input voltage is 260V, full loading ; I found the input current waveform was abnormal, please refer to the attachment waveform. i want to…
