Part Number: UCC28063A I have designed a PFC module using the UCC28063A aiming for 600W. The module works ok without load but with even a load of 2.5kOhm the output voltage drops to 286V. At the beginning of each AC line cycle the two phases have about…
Part Number: UCC28063 Other Parts Discussed in Thread: , UCC28064A Hi Sonal-san,
Any other change between UCC28063 and UCC28063A?
Just only you mentions before?
My customers want to know strictly.
Part Number: UCC28063A Dear Team,
our customer is planning to use the UCC28063A.
We got the question if CS / input @ pin 10 is used for something else than the OC comparator that is shown in the block diagram?
The customer would like to connect another…
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 result is…
Part Number: UCC28063A Tool/software: WEBENCH® Design Tools Hi,
Trying to design a 600W PFC unit using the UCC28063A I used the WEBENCH tool.
For the L1 and L2 the suggested NstoNp is 7.413m. Does this means that Np/Ns = 1/0.007413=135?
From the datasheet…
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.html#p1694…

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 388V…
Part Number: UCC28063A Hi team,
We want to check whether the device can support 85VAC input, 600Vdc output. And what's the max frequency of the devices? Thanks.
