Part Number: UCC28063A I found that the switching frequency is limited to 500kHz for UCC28063A on the introduction page ( http://www.ti.com/power-management/offline-isolated-dcdc-controllers-converters/power-factor-correction-pfc-controllers/products…
Part Number: UCC28063A Hi team,
My customer is using the UCC28063A EVM to do some tests. The customer do 0.1A-4A load transient, 5ms on (4A) 1s period to support huge current.
when 4A on, the Vout drop the current can support 4A. But the real test…
Part Number: UCC28063A Other Parts Discussed in Thread: PMP10116 Hello,
Regarding to the power factor on UCC28063A, my customer is asking a question.
(Question)
Do you have a data of power factor at 10 - 30% of rated output current under following…
Part Number: UCC28063A Good morning,
I am designing a 400W PFC with the UCC28063A.
My Vin range will be 184V RMS to 265V RMS.
To keep the inductor values small, I would like to use values of 114uH which will give a peak current of 7.58A at Vin …

Hi Sir,
May I have your help to review the UCC28063 SCH and Design calculator in the attachment?
Currently, we facing a output voltage drop issue in light load, Vout will drop from…
Part Number: UCC28063A I have used UCC28063A in bridgeless boost PFC, but there are some problems. Pls see the figures below.
Two auxiliary windings are used to acheve ZCD in positive and negative linecycle,respectively (see fig. 1), but the ZCD signal…
Hello John,
Thanks for sending the additional information. The schematic is drawn for a current limit set at 15A with the components values shown. You dont specify what power level is used in this application but 15A is a very high current limit and…
Part Number: UCC28063A Other Parts Discussed in Thread: UCC28070 My customer would like to know if it is possible to interleave four UCC28063A devices for a single output (from a single source)?
From some other posts it appears this will not work but…
Part Number: UCC28063A Hi
We are using UCC28063A and would like to use More Accurate Time Delay Circuit (Figure 26 from the datashet)
Any document or tool explaining how calculate below circuit?
Thanks!
